fix mcp consent org restore (#1126)

Stops Nova's saved active org from overriding the org picked on the MCP OAuth consent page.

- skips localStorage org restoration on `/oauth/consent`
- keeps normal Nova org restore behavior everywhere else

Testing:
- `bunx biome check --write packages/lib/auth-context.tsx`
- `bun run --filter @repo/web lint` passes with existing warnings
- `bunx tsc --noEmit --project apps/web/tsconfig.json` fails on existing unrelated type errors outside this change
