Claude b8ed763062 fix: Do not generate random password on Helm upgrade ...

Previously, when WP_ADMIN_PASSWORD was empty, the init container would
generate a random password and update the Secret. However, Helm upgrades
would start fresh containers and regenerate a new random password, causing
the Secret to not match WordPress's actual admin password.

Changes:
- Remove random password generation logic
- Require WP_ADMIN_PASSWORD to be explicitly set in values.yaml
- Exit with error if password is not provided during installation
- Only install WordPress once when database tables don't exist
- During upgrades, no installation occurs so password remains unchanged

This ensures:
1. Initial deployment: Admin must set WP_ADMIN_PASSWORD in values.yaml
2. Helm upgrades: No password changes occur (WordPress unchanged)
3. Helm rollbacks: Original password still works
4. Secret consistency: Secret always matches WordPress's actual password

Important for users:
- Initial deployment requires WP_ADMIN_PASSWORD in values.yaml
- If not provided, installation will fail with clear error message
- This prevents the password mismatch issue on upgrades
