user-record: validate JSON shell fields with valid_shell()

The user record loader currently uses a generic filename-or-path check
for shell and fallbackShell. This allows values that homectl rejects,
including relative names, control characters, colons, and trailing
slashes.

Use valid_shell() for all three record locations and cover the top-level,
matching per-machine, and status fallback fields at the loader boundary.

Fixes #43066
