Krzysztof kuhy Rudnicki 83d77884a0 Workout screen never moves when a rest starts; a sandbox flavor to prove it on the phone
The rest banner used to be inserted into the column only while a break ran,
so its arrival took height from the exercise list, shifted every tile down
and pushed the last one into scroll range. The strip is now a permanently
reserved 64 dp slot (muted "Rest / 00:00" while idle, Skip keeps its space),
the list is a non-scrolling column that scales down as a whole if it would
not fit (0.96 on the Pixel 6a with four tiles, pinned by a widget test at
the phone's logical size with the status bar simulated), and the activity is
locked to portrait. Verified on the real phone: only the tapped circle's
pixels change when a rest starts.

Verifying that needed a workout screen that today's already-logged workout
did not offer, so the app gained a `sandbox` product flavor beside `daily`:
com.kuhy.workout_app.sandbox installs side by side with its own data, refuses
every network connection at the socket layer, starts no LAN server for the
PC to pull from, keeps its /sdcard files beside the daily build's, wears a
red SANDBOX ribbon, and offers a SANDBOX section in Settings (wipe, mark
today not done, rest length in seconds). MainActivity answers the flavor and
carries a `WorkoutSandbox` logcat trace of every tap, break, save and
navigation. On Linux the same mode is WORKOUT_SANDBOX=1, driven under Xvfb by
scripts/run_sandbox_xvfb.sh. CI builds --flavor daily; .phone-deploy-flavor
tells phone_deploy.sh the same.

Set circles and the home icon buttons carry semantics labels so they can be
addressed by element (and by screen readers).
