chore: cleanup dead code + format with Pint

- Remove unused FeaturesController (empty stubs, no routes)
- Remove ConvertSpatialFile CLI command (unused; service used in LayerManager)
- Remove MigrateGeojsonToFeatures CLI command (one-shot migration, not referenced)
- Remove .claude/worktrees/ (11 old agent worktrees from June)
- Apply Laravel Pint formatting across 219 files (style only, no functional changes)

Tests: 101 passing (319 assertions)
API routes: unchanged (8 routes intact)
