Replace Redis/Sidekiq with Solid Queue/Cable/Cache and add CI tooling

- Replace Sidekiq with Solid Queue (database-backed job processing)
- Replace Redis-based Action Cable with Solid Cable
- Add Solid Cache for production/staging caching
- Add Mission Control Jobs dashboard at /madmin/jobs
- Add multi-database config for cache, queue, cable databases
- Add bin/ci local CI runner and bin/bundler-audit
- Update CI workflow: add bundler-audit, RuboCop cache, remove Redis/Node
- Remove bin/render-start-sidekiq.sh (Solid Queue runs in Puma)
