perf: reduce random re-renders across app caused by backend state strings

[plebe1us]

These random re-renders cause serious FPS drops sometimes, especially when loading a feed for the first time.

Not sure if it's possible to fix this on the frontend side, needs testing: https://t.me/seeditreact/10236

i'm actually not noticing bad FPS drops right now. lowered priority

not too good actually, with React Scan we can see there's too many rerenders caused by backend state changes, especially from the loading state strings displayed in the UI (such as the feed footer)
