Remove redis dependency

[gmmcal]

Rails 8 introduces the Solid Trifecta. They allow rails to operate many things under a database (like postgres) by default, and almost invalidates the need of using redis (for caching).

The goal is to get rid of

• pub/sub setup. This is a huge overkill take works great, but makes upgrades much harder for no good reason. Likely, the best approach to this is move this mechanism into ActiveJob
• Move cache towards solid_cache.
• Move cable towards solid_cable.
• Move ActiveJob towards solid_queue.
