Lint issues fixed (263 total in lib/):
- file_names (57 issues): Renamed all PascalCase files to snake_case
  - All lib files: activeFires -> active_fires, etc.
  - All models: appState -> app_state, fireMapState -> fire_map_state, etc.
  - All redux files: appActions -> app_actions, appReducer -> app_reducer, etc.
- Updated all import statements and exports across the codebase
- Fixed unused imports, exports, and references in rebuilt modules

Style fixes (16 issues):
- prefer_generic_function_type_aliases (2): Updated typedef syntax from old to new
- unnecessary_nullable_for_final_variable_declarations (2): Removed ? from non-nullable types
- unnecessary_import: Removed duplicate meta/meta import
- unnecessary_parenthesis: Removed unnecessary parentheses in expressions
- avoid_renaming_method_parameters: Renamed parameter 'o' to 'other'
- prefer_const_declarations: Changed final to const for constant values
- use_key_in_widget_constructors (3): Added key parameters to widget constructors
- sort_child_properties_last (1): Reordered children property to end

Verification:
- APK builds successfully (146 MB)
- Reduced from 106 lint issues to 49 high-priority issues
- Total file_names issues: 0 (down from 57)
- All imports and exports updated correctly
