feat: Major refactor, implement web, caching, better tests and build files

* Update golang version to 1.24
* Update multiarch Dockerfile to be more ISA agnostic
* Refactor existing code and properly structure project into modules
* Get rid of global variables except where necessary (go:embed)
* Add default values to Config
* Add webserver with templates to finally correctly serve videos and gifs
* Add tiny caching library to decrease api load and improve latency
* Improve Webhook data preparation by filtering out redundant links
  from the tweet text and properly attaching videos and gifs in separate
  webhook request by utilising new webserver
* Improve tests for filter function
* Improve bake definition for easier CI integration
