Krzysztof kuhy Rudnicki 600d0fd084 Migrate screen_locker to gatelock v0.2.0 per-output locking 
The lock now paints one container per live output instead of one window on
the primary, and claims the screen through an Arbiter at RANK_SCREEN_LOCKER
so the wake alarm can outrank it.

The fan-out happens at the widget factory, not the render loop. Painting a
screen here is not a pure function -- the ~20 clear_container() flows record
workouts, credit weeks and branch on state while they paint -- so re-running
a flow per surface would double those side effects. Instead `_label`,
`_button_row` and friends build N copies and return a group that mirrors
later configure calls to all of them, and a flow body still runs once. Frame
groups nest, so `_button(button_row, ...)` reads exactly as it did.

The degenerate case carries as much weight as the general one: the status
window, the post-sick-day verify window and the relaxed-day prompt have no
lock and no surfaces, and share this same factory. They get a group of
exactly one frame and behave as they always did.

Text boxes are the one thing that cannot be shared. Entries fan out over a
single StringVar, but tk.Text has no such variable, so the sick-day
description genuinely diverges per monitor; TextGroup.get() returns whichever
copy was actually typed into, preserving "answer on any monitor".

Tests: the suite hung rather than failed on first run, which is the trap
gatelock's own conftest documents -- screen_locker patches its own `tk`, but
LockWindow builds Toplevels through gatelock's, and real tkinter over a
MagicMock root recurses without bound. `_gatelock_fixtures` closes that and
redirects the runtime dir so no test can stand a production locker down.
Every other test runs single-output, where fan-out is unobservable, so
test_surface_fanout runs on two outputs; each assertion was checked by
cropping the group loops to the primary and confirming it goes red.

874 tests, 100% branch coverage, pre-commit clean, no lint suppressions.
