Add Gitea email configuration and document SMTP authentication troubleshooting

Changes:
- Configure Gitea mailer with Titan Email SMTP settings
- Add SMTP_AUTH = PLAIN for authentication method specification
- Update SMTP password in vault (vault_gitea_smtp_password)

Email Status:
Currently non-functional due to SMTP authentication rejection by Titan Email
servers. Error: 535 5.7.8 authentication failed

Troubleshooting Performed:
- Tested both port 587 (STARTTLS) and 465 (SSL/TLS)
- Verified credentials work in webmail
- Tested AUTH PLAIN and AUTH LOGIN methods
- Removed conflicting TLS settings
- Both authentication methods rejected despite correct credentials

Root Cause:
The issue is NOT a Gitea configuration problem. Titan Email SMTP server
is rejecting all authentication attempts from the VPS (69.62.119.31)
despite credentials being correct and working in webmail.

Possible causes:
- SMTP access may need to be enabled in Hostinger control panel
- VPS IP may require whitelisting
- Account may need additional verification for SMTP access
- Titan Email plan may not include external SMTP access

Documentation:
Created comprehensive troubleshooting guide at:
docs/gitea-email-troubleshooting.md

Files Modified:
- roles/gitea/templates/app.ini.j2 (+1 line: SMTP_AUTH = PLAIN)
- docs/gitea-email-troubleshooting.md (new file, complete troubleshooting log)
- host_vars/arch-vps/vault.yml (updated SMTP password - not committed)

Next Steps:
- Check Hostinger control panel for SMTP/IMAP access toggle
- Test SMTP from different IP to rule out IP blocking
- Contact Hostinger/Titan support for SMTP access verification
- Consider alternative email providers if Titan SMTP unavailable

+# Gitea Email Configuration Troubleshooting
+
+## Summary
+
+Attempted to configure Gitea email functionality using Titan Email (Hostinger) SMTP service. Email sending is currently **non-functional** due to SMTP authentication rejection by Titan Email servers.
+
+## Configuration Details
+
+### Email Provider
+- **Provider:** Titan Email (by Hostinger)
+- **Account:** hello@jnss.me
+- **SMTP Server:** smtp.titan.email
+- **Ports Tested:** 587 (STARTTLS), 465 (SSL/TLS)
+
+### Gitea Configuration
+```ini
+[mailer]
+ENABLED = true
+PROTOCOL = smtp+starttls
+SMTP_ADDR = smtp.titan.email
+SMTP_PORT = 587
+FROM = hello@jnss.me
+USER = hello@jnss.me
+PASSWD = <vault_gitea_smtp_password>
+SUBJECT_PREFIX = [Gitea]
+SEND_AS_PLAIN_TEXT = false
+SMTP_AUTH = PLAIN
+```
+
+## Issue Description
+
+Gitea fails to send emails with the following error:
+```
+Failed to send emails: failed to authenticate SMTP: 535 5.7.8 Error: authentication failed
+```
+
+## Troubleshooting Performed
+
+### 1. Credential Verification
+- ✅ **Webmail access:** Successfully logged into https://mail.titan.email/ with credentials
+- ✅ **Send/Receive:** Can send and receive emails through webmail interface
+- ✅ **Password confirmed:** Tested multiple times, credentials are correct
+
+### 2. SMTP Connectivity Tests
+- ✅ **Port 587 (STARTTLS):** Connection successful, TLS upgrade successful
+- ✅ **Port 465 (SSL/TLS):** Connection successful with implicit TLS
+- ✅ **DNS Resolution:** smtp.titan.email resolves correctly to multiple IPs
+
+### 3. Authentication Method Testing
+
+**Manual SMTP tests from VPS (69.62.119.31):**
+
+```python
+# Test Results:
+AUTH PLAIN:  ❌ 535 5.7.8 Error: authentication failed
+AUTH LOGIN:  ❌ 535 5.7.8 Error: authentication failed
+```
+
+**Both authentication methods rejected by server despite correct credentials.**
+
+### 4. Configuration Iterations Tested
+
+#### Iteration 1: Port 465 with smtps
+```ini
+PROTOCOL = smtps
+SMTP_PORT = 465
+```
+**Result:** Authentication failed (535)
+
+#### Iteration 2: Port 587 with smtp+starttls
+```ini
+PROTOCOL = smtp+starttls
+SMTP_PORT = 587
+```
+**Result:** Authentication failed (535)
+
+#### Iteration 3: Explicit AUTH PLAIN
+```ini
+PROTOCOL = smtp+starttls
+SMTP_PORT = 587
+SMTP_AUTH = PLAIN
+```
+**Result:** Authentication failed (535)
+
+#### Iteration 4: Removed conflicting TLS settings
+Removed:
+- `ENABLE_TLS = true` (conflicted with PROTOCOL)
+- `SKIP_VERIFY = false` (deprecated)
+
+**Result:** Authentication still failed (535)
+
+### 5. Debug Output Analysis
+
+SMTP conversation debug output revealed:
+```
+send: 'AUTH PLAIN AGhlbGxvQGpuc3MubWUASGVsbG8xMjMh\r\n'
+reply: b'535 5.7.8 Error: authentication failed: \r\n'
+
+send: 'AUTH LOGIN aGVsbG8Aam5zcy5tZQ==\r\n'
+reply: b'334 UGFzc3dvcmQ6\r\n'
+send: 'SGVsbG8xMjMh\r\n'
+reply: b'535 5.7.8 Error: authentication failed: UGFzc3dvcmQ6\r\n'
+```
+
+**Analysis:** Server accepts both AUTH PLAIN and AUTH LOGIN in EHLO response but rejects actual authentication attempts for both methods.
+
+## Root Cause Analysis
+
+### What Works
+- ✅ SMTP server connectivity (both ports)
+- ✅ TLS/STARTTLS negotiation
+- ✅ Webmail authentication with same credentials
+- ✅ Email sending through webmail
+
+### What Doesn't Work
+- ❌ SMTP AUTH PLAIN from VPS
+- ❌ SMTP AUTH LOGIN from VPS
+- ❌ Both fail with identical error: 535 5.7.8
+
+### Conclusion
+
+**The issue is NOT a Gitea configuration problem.** The SMTP server is actively rejecting authentication attempts despite:
+- Correct credentials (verified in webmail)
+- Proper TLS establishment
+- Correct authentication protocol usage
+
+## Possible Causes
+
+1. **SMTP Access Disabled:** Titan Email may require SMTP/IMAP access to be explicitly enabled in Hostinger control panel or Titan settings
+2. **IP-Based Restrictions:** VPS IP (69.62.119.31) may be blocked or require whitelisting
+3. **Account Verification Required:** Account may need additional verification for SMTP access
+4. **Service-Level Restriction:** Titan Email plan may not include SMTP access for external applications
+5. **Missing Activation:** SMTP feature may require separate activation from webmail access
+
+## Attempted Solutions
+
+### Configuration Changes
+- [x] Tested both port 587 (STARTTLS) and 465 (SSL/TLS)
+- [x] Tried AUTH PLAIN and AUTH LOGIN methods
+- [x] Removed conflicting TLS settings (ENABLE_TLS, SKIP_VERIFY)
+- [x] Updated password in vault and redeployed
+- [x] Verified minimal clean configuration
+
+### External Tests
+- [ ] Test SMTP from different IP (local machine vs VPS)
+- [ ] Check Hostinger control panel for SMTP toggle
+- [ ] Contact Hostinger/Titan support
+- [ ] Verify account has SMTP privileges
+
+## Recommendations
+
+### Immediate Next Steps
+1. **Check Hostinger Control Panel:**
+   - Log into hpanel.hostinger.com
+   - Navigate to Emails → hello@jnss.me
+   - Look for SMTP/IMAP access toggle or settings
+
+2. **Test from Different IP:**
+   - Test SMTP authentication from local machine
+   - If successful: IP blocking issue (request VPS IP whitelist)
+   - If failed: Account-level restriction
+
+3. **Contact Support:**
+   - Provide error: "535 5.7.8 authentication failed"
+   - Request SMTP access verification for hello@jnss.me
+   - Ask if SMTP requires separate activation
+
+### Alternative Email Solutions
+
+If Titan Email SMTP cannot be resolved:
+
+1. **Use Different Email Provider:**
+   - Gmail (with App Passwords)
+   - SendGrid (free tier: 100 emails/day)
+   - Mailgun (free tier: 5,000 emails/month)
+   - AWS SES (free tier: 62,000 emails/month)
+
+2. **Use Local Mail Server:**
+   - Install Postfix on VPS
+   - Configure as relay
+   - More complex but full control
+
+3. **Disable Email Features:**
+   - Set `ENABLED = false` in [mailer]
+   - OAuth account linking won't work
+   - Password reset requires admin intervention
+   - No email notifications
+
+## Current Status
+
+**Email functionality: DISABLED**
+
+Configuration is correct but non-functional due to SMTP authentication rejection by Titan Email servers.
