chore: Fix lint issues

This commit addresses several lint warnings by:
- Explicitly typing static final fields in query classes.
- Adding the `async` keyword to methods that return Futures where it was missing.
- Using `var` for local variables where the type can be inferred.

Additionally, the `avoid_types_on_closure_parameters` and `omit_local_variable_types` lint rules have been enabled in `analysis_options.yaml`. The `unsafe_variance` rule has been temporarily disabled due to false positives.
