Adds triage coverage bitmask workers and services

What does this MR do and why?

Introduce the triage coverage bitmask infrastructure: encode per-project, per-trigger type AI-triage capabilities into two integer bitmasks on security_inventory_filters.

The security inventory UI needs to filter and sort projects by triage coverage, but querying eligibility services at read time is too expensive. Instead, TriageCoverage::RecomputeService reads the current capability state from eligibility services (DependencyManagement::SecurityUpdate::Eligibility and Vulnerabilities::AiTriage::Eligibility for the other types), encodes the result into two bitmasks via CapabilityBitmask, and persists them via TriageCapabilitiesUpdateService. Two Sidekiq workers schedule and execute these bulk upserts: ScheduleUpdateWorker fans out in batches of 100 projects, and UpdateWorker invokes the recompute service.

This MR is the second in a series. The next MR wires up the call sites (scan profile attach/detach/update/delete) that trigger this recompute pipeline, so no caller in this code yet.
