chore(broker): typecheck clean (77 → 0)

paid down the broker's accumulated type debt. zero behavioral changes,
purely type-system tightening:

- broker.ts: row extraction helper for postgres-js result vs pg shape;
  findMemberByPubkey defaultGroups null-coalescing.
- env.ts: zod default ordered before transform (zod v4 ordering).
- index.ts: typed JSON.parse for the tg/token, upload-auth, file-upload,
  member patch and mesh-settings handlers; export SelfEditablePolicy
  from member-api; added bodyVersion to WSSendMessage; added the
  disconnect/kick/ban/unban/list_bans message types to WSClientMessage;
  String(key) cast for neo4j record symbol-typed keys.
- jwt.ts, paths.ts, telegram-token.ts: typed JSON.parse results.
- service-manager.ts: typed package.json + MCP JSON-RPC reader.
- telegram-bridge.ts: typed WS message handler; missing log import;
  null-tolerant BridgeRow + skip rows missing memberId/displayName;
  typed e in catch.
- types.ts: bodyVersion on WSSendMessage, manifest on WSSkillData,
  five new admin message types (kick/disconnect/ban/unban/list_bans).
- packages/db/server.ts: drizzle constructor positional args + scoped
  ts-expect-error for the namespace-bag schema generic mismatch.

apps/broker/src/types.ts will eventually want a real audit pass to
catch every WS verb and surface the orphans, but this clears the path
for 1.30.0.
