Implement Integration Tests for Supabase RLS Policy Enforcement Across All Tables

[temma02]

Description

Build integration tests that systematically verify Row Level Security policies are enforced across every table in the schema, ensuring complete coverage of the authorization layer.

Requirements and Context

• Security: Every table with sensitive data must have verified RLS enforcement
• Testing: Extend supabase/tests/rls/policy-verification.test.ts
• Documentation: Update docs/rls-audit.md with the full coverage matrix

Suggested Execution

Branch: test/issue-049-supabase-rls-full-coverage-tests

Implement Changes

• Enumerate all tables and add RLS enforcement tests for each
• Test that anonymous access is denied for all protected tables
• Test that authenticated users can only access their own rows
• Update docs/rls-audit.md with a complete per-table coverage matrix

Test and Commit

• Every protected table must have RLS enforcement tests
• Cover anonymous denial and per-user isolation
• Update the RLS audit matrix to reflect full coverage

Example Commit Message

test(rls): add integration tests for RLS enforcement across all tables

- Enumerate and test RLS for every protected table
- Test anonymous denial and per-user isolation
- Update rls-audit.md with full coverage matrix

Guidelines

• Use separate Supabase client contexts per simulated user
• Never use the service role key in RLS enforcement tests
• Keep the coverage matrix in sync with the migration files
