fix: resolve ESLint parse errors, unused imports, and TS unknown type errors

- Fix catch blocks with inline comments that broke parsing
- Remove unused Edit3 import from ClientReferrals
- Add eslint-disable for set-state-in-effect (intentional fetch-on-mount pattern)
- Fix 'e' is of type 'unknown' errors with instanceof checks
