Summary by cubic

Hardened admin OAuth routing by narrowing regex captures before decoding. Prevents decoding undefined and unsafe index access, with no behavior changes.

• Bug Fixes
  • Use optional chaining on regex matches and check for presence before decode.
  • Replace direct match[1] indexing with named locals to satisfy strict noUncheckedIndexedAccess.
  • Start, events, and cancel endpoints keep the same behavior and responses.
