spoopyghosty0 f7108c0ca4 Fix: a page change could die when a background thread set a control property mid-update
Flet packs a patch by iterating each control's _values dict; Prop.__set__ adds/removes keys there without a lock.
A property set on a background thread (the live Frame card's sample, job progress, the library loader) while the
event loop packed a patch raised "dictionary changed size during iteration" and the update was lost (seen in CI:
a sidebar click left the old page showing). serialize_flet_updates() now makes property writes take the same
re-entrant lock as patches (app.FLET_LOCK). Reproduced with Flet's own encoder: 16 failures in 4 s before, none
after; test_property_writes_wait_for_a_patch_being_packed. The showcase server and ui_smoke serialize like the app.
Tour re-recorded with the fix (clean, no fallback clicks).
