UI improvements

[unbiaseduser]

I have made some qol improvements on various parts of the ui:

• Use Material components instead of regular Android components. If you want to implement Material You theme later, you pretty much have to use them. Also, as I explained earlier, you don't have to avoid it and they simply look nicer.
• Fix toolbar not showing on light mode.
• Fix a bug where you can pick a future time in today.
• The date formatting now expands to years, months and weeks. Also, if any time unit is 0, it's hidden. Fixes option for years months days hours minutes #24
• The Create activity is more optimized for one handed usage. (all elements are positioned lower).

Hold on a sec. Please wait for me to fix time formatting, it's harder than I thought.

I'm merging without checks because they don't want to run, I really hope there's no build issues.
