feat(mcp): add Codex OAuth support

[timothyfroehlich]

Summary

• add Supabase OAuth 2.1 verification and RFC 9728 discovery for the PinPoint MCP endpoint while preserving the existing Claude bearer path
• bind the approved Codex client to the exact MCP audience through a custom access-token hook and application allowlist
• add request/write rate limits, MCP safety annotations, project Codex approval policy, the 200-character PinballMap reason cap, and an activation/runbook flow

Validation

• pnpm run check
• pnpm run test (2,722 passed)
• Bazzite PGlite integration suite (709 passed)
• focused real-Postgres OAuth hook integration test (3 passed)
• full preflight attempted; its OAuth path passed, but the run was blocked by the existing discord-config-rls singleton-state failure and a local worktree port collision with another active Supabase project

Tracking

• PP-u4ab.16
• PP-u4ab.3
• PP-u4ab.15
