fix: correct audit event names, attachment deletion, redirect safety, and add account deactivation check

- Fix audit event names in CLI prune/clear commands from `cli.seo.*` to `cli.seo_meta.*`
- Refactor `_delete_attachment_file` to accept full attachment dict instead of storage_path string, using directory and stored_name fields with ATTACHMENTS_DIR
- Add `safe_next` validation for referer header in validation error redirect and media redirect
- Add `is_active` check in login router to reject deactivated accounts with "Account is deactivated" error
- Replace raw `request.headers.get("Referer")` with `redirect_back()` utility in bookmarks, polls, reactions, and votes routers
- Move `mark_conversation_read` call from `get_conversation_messages` to `messages_page` to avoid side effects during message retrieval
- Fix poll audit link to use `option.get("label")` instead of `option.get("text")`
- Add `VOTABLE` set validation in votes router to reject invalid target types with 400 response
- Strip control characters (0x00-0x20) from URLs in `_safe_url` instead of simple strip
- Add `__getattr__` fallback in services `__init__.py` for dynamic attribute access
