refactor: Consolidate script imports to use main.js bundle

- dashboard.templ: Replaced individual script tags with single main.js import
- admin_users.templ, custom_section.templ: Minor formatting/cleanup
- docs.templ: Updated script imports (excluded from Alpine conversion per user request)
- api.ts, docs.ts, password_validation.ts: Minor updates for compatibility
