Refactor ProjectService::bulkAction to accept full payload array and
return structured {updated, skipped, warnings}. Add bulkUpdateRegions
using PG raw bitmask expr (region_mask | add) & ~remove & 255.
Add stubs for bulkUpdateDays/bulkUpdateLimit (Tasks 3-4). Update
controller to pass merged payload and return service result directly.
Un-todo Task-1 region validation test; add regions bitmask test (18/20).
Update phpstan-baseline: actingAs count 5->6, restore match.unhandled.
