The planning save paths only copied shifts 1-2 from the request model
onto the PlanRegistration entity, silently dropping shifts 3-5 even
though the entity columns exist and the read path sums all five.
UpdateByCurrentUserNam (the path reached by the Flutter worker app via
gRPC) was missing the assignments entirely.

Adds a C# integration test that round-trips all 5 shifts through
Update() + EF, and a Playwright E2E that exercises the full web UI
save/reload of all 5 shifts in the workday-entity dialog — both serve
as regression guards.

- PlanningServiceMultiShiftTests: Update() dereferences currentUserAsync.Id;
  stub IUserService.GetCurrentUserAsync to return EformUser { Id = 1 } so the
  persistence assertion exercises the real save path instead of swallowing an
  NRE as "ErrorWhileUpdatingPlanning".
- dashboard-edit-multishift.spec: simplify pickTime to match the existing
  helper pattern and shift all 5 slots away from 00:xx (Material timepicker's
  "12" sits at a non-rotateZ position that broke the click locator).

…s.Auth)

CI build failed with CS0246: EformUser lives in
Microting.eFormApi.BasePn.Infrastructure.Database.Entities, not
...Infrastructure.Models.Auth.

Verified with `dotnet build` locally: 0 errors.

The rotateZ-selector approach breaks for hour=0 (the "12" position doesn't
render with a stable `rotateZ(0deg)` computed style), so every break-time
click (00:05/00:10/…) timed out. Switch to coordinate-based clicks on
`.clock-face`, same strategy as time-planning-settings.spec.ts, which
handles h=0 uniformly.

… test

The workday-entity dialog only renders shift rows 3-5 when
thirdShiftActive/fourthShiftActive/fifthShiftActive are true on the
assigned site. CI defaults them to false, so the test timed out
waiting for [data-testid="plannedStartOfShift3"]. Open the
assigned-site dialog via #firstColumn0 first and tick the three
cascading checkboxes, then proceed with the day-cell edit.

The assigned-site dialog gates the 4th checkbox on `data.thirdShiftActive`
and the 5th on `data.fourthShiftActive` — both bound to the dialog input
snapshot, not the live form control. So each flag only materialises after
a save + reopen. Loop three times: open dialog, tick the next checkbox,
save, close.

The prelude was ticking thirdShiftActive on row 0 (#firstColumn0) but
the test edits row 3 (#cell3_0), so the workday dialog still opened
with the default 2-shift assigned site and timed out waiting for
plannedStartOfShift3. Align the assigned-site dialog target with the
day-cell target.
