feat(admin): add a root-only database studio tab

[ryanbarlow97]

A new Database tab in the staff panel, root only (use_database), for browsing, querying and editing the site's databases.

What it does

• /admin/database lists the databases this site can reach: province.db, its CoreProtect (Main on www, Dev on dev; read-only), and the Precedent/patch notes Postgres (www only). It shows tables, size, audited query count and access, with search and sortable columns.
• /admin/database/{id} opens a studio: table sidebar with search, expandable columns (type, PK) and row estimates; query tabs (kept in local storage) and table tabs; an editor with line numbers, Tab indent and Ctrl/⌘+Enter; a draggable editor/results split; a results grid with sticky header, row numbers, NULL/blob display, client sort, a cell inspector (JSON pretty-printed) and CSV copy/download.
• Table tabs page through the table on the server with WHERE filter, page size, column sorting and Open as query.
• Edit mode on writable databases asks for confirmation (showing the SQL) before running, then refreshes the table list.

Safety

• Reads: SQLite mode=ro + query_only, Postgres read-only transactions; 1,000-row cap; 10 s limit (progress handler / SET LOCAL statement_timeout); one SQLite statement per query.
• CoreProtect: through the existing guarded reader (single reader, 3 s budget) with a new capped Reader.query, so a studio query can't hold off CoreProtect's writes for long or pull millions of rows. Never written.
• Edits: one transaction, foreign keys on, same limits. admin_audit can't be changed, dropped or have triggers changed; ATTACH is refused in both modes.
• Every browse, query and edit is audited (database.read / database.write) with the SQL (first 2,000 chars), outcome and counts. POSTs need the site's Origin.
• Secret-looking text columns (token_hash, refresh_token, …) are masked in results (display only). Integers past 2^53 travel as text; blobs as size + hex prefix.

Tests

Backend: 13 new tests (root-only, read-only enforcement, edits + audit, audit-log protection, ATTACH, masking, row cap, timeouts, CoreProtect schema/browse/budget, Postgres read-only transactions with a fake connection); 715 passed across auth/coreprotect/servers/rail/luckperms/dbstudio. Frontend: 8 new studio tests + AdminNav root-only tab; 141 admin tests pass; tsc, oxlint, oxfmt clean.

Checked in a local lab (real routes, temp province.db, a 60k-row fake CoreProtect, headless Chromium at 1440 and 390 wide): list, query, edit confirmation, CoreProtect browse and aggregate query, SQL error display.

📝 Summary

Summary by CodeRabbit

• New Features
  • Added an admin database area for viewing available databases, inspecting schemas and browsing, filtering and sorting table data.
  • Added a SQL editor for running queries, with results that can be copied or downloaded as CSV. Changes require confirmation, and read-only databases cannot be edited.
  • Database access is restricted to administrators with the required permission; database activity is audited.

The pull request adds a database administration studio. Staff with the required capability can inspect database sources and schemas, browse tables, and run queries through the backend API and admin interface.

Changes: Database administration

Layer / File(s)	Summary
Database query execution backend/src/dbstudio/studio.py, backend/src/coreprotect/reader.py, backend/src/dbstudio/test_studio.py	The studio discovers SQLite and Postgres sources and executes bounded queries with source-specific permissions, timeouts, and result handling. Tests cover query limits, masking, errors, and transaction behaviour.
Schema, browsing, and overview backend/src/dbstudio/studio.py, backend/src/dbstudio/test_studio.py	The studio returns schema details, validates table-browse inputs, and reports source availability, table counts, and sizes. Tests cover schema and browse behaviour.
Access-controlled API and auditing backend/src/api/database_routes.py, backend/src/api/admin_routes.py, backend/src/auth/roles.py, backend/src/dbstudio/test_studio.py	The API adds overview, schema, browse, and query endpoints. It requires the use_database capability, disables response caching, validates requests, and records operation outcomes.
Admin navigation and database list frontend/app/components/admin/AdminNav.tsx, frontend/app/components/admin/AdminNav.test.tsx, frontend/app/components/admin/database/DatabaseList.tsx, frontend/app/admin/database/*, frontend/lib/admin/database.ts, frontend/app/components/admin/database/Database.test.tsx	The admin navigation displays the Database link when the fetched capabilities include use_database. The database list displays, sorts, and filters source details. Admin routes render the list and selected database studio.
Query editor, browsing, and results frontend/app/components/admin/database/DatabaseStudio.tsx, frontend/app/components/admin/database/ResultGrid.tsx, frontend/app/components/admin/database/SqlEditor.tsx, frontend/app/components/admin/database/studioStyles.ts, frontend/app/components/admin/database/Database.test.tsx	The studio adds query and table tabs, query-text persistence, edit confirmation, and table-browsing controls. The editor and result grid support query entry, sorting, copying, and CSV output.

Merge Risk: 🟡 Moderate · up to 6dcec

Opening an exported CSV in a spreadsheet can evaluate player-controlled formulas, and transaction-control queries can report failure after running. Fix both before merging.

Review comments at @backend/src/dbstudio/studio.py:
- Around line 155-162: Update the authoriser’s `check` function to deny
`SQLITE_TRANSACTION` for user statements. Disable the authoriser before `_site`
performs its internal `COMMIT` and before the exception handler performs
`ROLLBACK`, so both transaction-control operations remain allowed.

Review comments at @frontend/lib/admin/database.ts:
- Around line 76-79: Update toCsv so string cells beginning with =, +, -, @,
tab, or CR are prefixed with a single quote before CSV escaping; leave numeric
cells unchanged. Apply this sanitisation to row values while preserving the
existing field escaping and column-header handling.
