refactor: code quality cleanup — remove any types, add logger, rename Kine to Tabata

- Phase 0: Rename all Kine references to Tabata (types, files, imports, i18n, analytics events)
- Phase 1: Add test coverage for tabataProgramStore, workoutProgramStore, and color utils (47 tests)
- Phase 2: Remove all `any` types from production code with proper typed replacements
- Phase 3: Replace ~60 raw console.* calls with __DEV__-gated logger utility
- Phase 4: Verify .DS_Store housekeeping (already clean)

0 TypeScript errors, 583/583 tests passing.
