feat: Refactor rides app with unique constraints, mixins, and enhanced documentation
- Added migration to convert unique_together constraints to UniqueConstraint for RideModel. - Introduced RideFormMixin for handling entity suggestions in ride forms. - Created comprehensive code standards documentation outlining formatting, docstring requirements, complexity guidelines, and testing requirements. - Established error handling guidelines with a structured exception hierarchy and best practices for API and view error handling. - Documented view pattern guidelines, emphasizing the use of CBVs, FBVs, and ViewSets with examples. - Implemented a benchmarking script for query performance analysis and optimization. - Developed security documentation detailing measures, configurations, and a security checklist. - Compiled a database optimization guide covering indexing strategies, query optimization patterns, and computed fields.
