Internal improvements and some fixes 🩹⌚

While I continue working on the Spotify integration (we're getting there!) I pushed some fixes and improvements.

• The most noticeable change you'll see in this version is a new time picker. It's better than the previous one, which had many issues. I know it's a big change so let me know if you face any problem using it!
• There's also a new error page that lets you know when things went wrong and where you can also report details so I can find and fix the issue. I hope you don't get to see it but, in case you do, it should be more helpful than the previous silent crashes.

Aside from that, most changes are internal and focused on making things easier to change in the future.
I've been extremely busy moving into my new apartment (and I also started a new job!) so my development schedule went out the window.
Thanks for sticking with me while I adjust to these changes ❤️ I'm grateful for your continuous support!
