WearOS support

[TheLastProject]

Fixes #25

TODO:

• Some kind of confirmation a device is trusted (feat(bluetooth): Add trusted device pairing and encrypted sync #3223)
• Notification icon fixes (icon is too small now, see feat(bluetooth): Add trusted device pairing and encrypted sync #3223 (comment), fixed in Improve notification icons #3251)
• String consistency ("Wear" or "WearOS", not both interchangeably) (Consistently use Wear OS naming #3249)
• Document WearOS implementation and how to implement it for other apps in a file similar to CONTENT_PROVIDER.md in docs/ (Add WearOS Bluetooth server documentation #3241)
• Fastlane screenshots (required for Google Play, I'll make them) (Add WearOS screenshots and description change #3243)
• Versioning changes (WIP: Versioning and CHANGELOG changes for new Wear OS setup #3247)
• Update privacy policy (Update privacy policy #3255)
• Additional testing on Android 11 and below <- Tested flow on an old Android 9 device, worked just fine
• Test the app in an actual store

TODO but can wait until after the first release:

• Better status indicator (having it on the bottom makes it hard to see the current state, need to find different placement that won't make the card list jump) (Always display sync status on screen #3242)

For current versioning plan see #3247, related F-Droid thread: https://forum.f-droid.org/t/question-about-submitting-a-wearos-companion-app-to-f-droid/34580

Just one thing remaining: taking the watch to an actual store and seeing if it works well with the scanner and then this can be merged and released :)

Just got a crash on my test device when just starting Catima. But starting it a second time worked fine:

Worked around the crash in #3259

[TheLastProject]

Tested it with the self-scan at the local Albert Heijn. Worked fine, bit finicky at the second checkout scanner but no issues. I can see people like this over taking their phone out of their pocket/bag.

Is this perfect? No. Especially not with the weird random foreground service crash I got once.

Is it good enough for people to start using? Yeah, I definitely think so!

Weblate set up for the new Wear OS component, so translators can start translating :)
