I made some UI rehauls again lol

• Current day receives theis blur effect which kinda looks like real light bouncing inside a box under the current day
• The accent colour of the app is now brown, as I am trying to make the app feel more like paper, which will become more obvious as i later add paper elements and views inside the app.
• My last update released a new account backend, which meant some users were not able to log in, so i decided to nuke the database and reset everything 💀 but anyway it worked and i upgraded the server to be better at handling this
• The sheet to add a shared timetable is improved, with blur effects and stuff, and that tiemtable preview has gotten much better it was pretty bad before ngl
