Configurable PII entity types and custom regex patterns

- Chrome extension options page: enable/disable PII entity types per-request
- Custom regex patterns: add/edit/remove user-defined regex rules with replacement text
- New API endpoints: `GET /api/pii/labels`, `GET/POST /api/pii/patterns`, `PUT/DELETE /api/pii/patterns/{id}`
- Backend `MaskText` accepts `enabled_labels` to filter which PII types are masked
- Entity deduplication: overlapping spans resolved by length, custom regex wins ties

- **Backend URL** — The Kiji Privacy Proxy server address (default: `http://localhost:8081`)
- **Intercept domains** — URL match patterns where the extension is active (one per line)
- **PII entity types** — Check or uncheck PII labels from the model to control which entity types get masked per-request. A "Disable all / Enable all" toggle is provided. Changes are persisted to `chrome.storage.sync` and sent as `enabled_labels` with each PII check.
- **Custom patterns** — Add user-defined regex rules on top of the ML model. Each pattern has a label, regex, and optional replacement string. Patterns are persisted server-side in SQLite. A live preview field lets you test a regex against sample text before saving. Patterns can be edited or removed inline.
