feat: Enhance group labels and relations management

[BIA3IA]

Introduce new features for managing group labels, including CRUD operations for WhatsApp groups, improved search functionality, and validation to prevent deletion of labels assigned to groups. Implement cascade delete for group label relations and ensure platform-specific operations are handled correctly. Add a new role and permissions for web users.

Walkthrough

The change adds cascading deletion for Telegram and WhatsApp label relations. Label mutations now require an explicit platform and target one relation table. Group searches restrict relations and label filters to the group’s platform. Tests cover both behaviors.

Changes

Group label platform safety

Layer / File(s)	Summary
Relation cascade schema and migration src/db/schema/tg/groups.ts, src/db/schema/wa/groups.ts, drizzle/0015_uneven_deathstrike.sql, drizzle/meta/..., package.json, package/package.json, tests/group-label-cascade.test.ts	Telegram and WhatsApp label-relation foreign keys now use ON DELETE cascade. The migration metadata records the schema state. Package versions are 0.18.0. Tests verify the cascade declarations and migration.
Platform-specific label mutations src/routers/groups/labels.ts, tests/group-label-platform-isolation.test.ts	tagGroup and untagGroup require type, validate the matching group table, and modify only the matching relation table. Tests cover overlapping group IDs.
Platform-specific label searches src/routers/groups/search.ts, tests/group-label-platform-isolation.test.ts	Label joins and required or excluded label filters compare relation and group platform types. Tests verify the same-platform conditions.

Merge Risk: 🔵 Low · up to 165f9

The change improves platform isolation and cleans up group-label relations automatically, but existing callers must now provide a platform value and the database migration changes deletion constraints across both platforms. The PR is mergeable with explicit owner awareness or follow-up on client compatibility, migration recovery, and proof of cascade behavior.

inspect each Telegram and WhatsApp relation foreign-key ADD CONSTRAINT statement
individually and verify it contains ON DELETE cascade, rather than relying on a
global cascade count.

Audited against the PR scope and repository standards. Typecheck, Vitest suite (18 tests), package build, and npm pack dry-run pass. Platform-specific label operations and cascade migration are correctly implemented.
