android: clearer warnings on the unsupported device screen

[thisisAcidic]

the unsupported device screen right now just says "Not supported" and lists what works, but doesnt actually tell people their device wont work or to stop reporting it. people bypass, app fails as expected, then they open issues we cant do anything about. this just makes the screen blunt about it.

what changed

three strings in res/values/strings.xml:

• screen body: now explicitly says "your device is not on the list... not something LibrePods can fix... bypass exists but the app will most likely not function... please dont open issues or ask in Discord"
• bypass confirmation dialog (regular build): warns "most likely wont work, developers cannot fix this, do not report problems caused by bypassing"
• bypass confirmation for play build: same kind of message

not changed

values-zh-rTW/strings.xml still has the old weaker chinese translations. didnt touch them since i dont speak chinese. either keep as-is or remove those four entries so it falls back to english (which now has the new strict text). lmk if you want me to do something there
