Fix lint errors: remove unused imports, fix floating promises, clean up eslint directives

- Remove unused eslint-disable directives from multiple files
- Fix floating promise in baileys-event-stream.ts by adding void operator
- Remove unused import recordMessageRetry from messages-send.ts
- Prefix unused variable beforeTime with underscore in test file
- Remove incorrect eslint-disable comments that were causing prettier errors

Progress: Reduced from 68 to 35 errors. Remaining errors are primarily max-depth issues.
