fix: resolve all warnings (59 warnings → 0)

- Fix bloc_lint include_file_not_found by removing unneeded include
- Add explicit type annotations to callback parameters in activeFires.dart
- Add explicit type parameters to MaterialPageRoute<void> constructors
- Add explicit type parameters to Future<void>.delayed() calls
- Fix error handler signatures: (Object err, StackTrace stack)
- Remove 'const' from genericMap() widget construction (StatefulWidget)

All strict analysis errors and warnings now resolved (0 errors, 0 warnings).
Remaining 339 issues are info-level linting suggestions.
