Mohamed BoudraandGitHub adc9b3b43c Preserve loader behavior while reducing hidden work (#1996)
* fix(app): preserve loader behavior in retained panels

Keep the running footer mounted across panel switches. Inactive loaders stop their animation work, then realign to the original wall-clock phase before they become visible.

* perf(app): remove inactive loader wrapper worklet

* perf(app): pause hidden turn elapsed timers

* perf(app): reduce loader animation work

Keep one wall-clock-aligned clock for visible loaders and detach retained
hidden loaders without unmounting them. Preserve the 950 ms sequence and
reduced-motion behavior.
