LS-T1 of the tablet lock-screen redesign.
Adds 3 module-level helpers in tablet_controller.py:
_initials_from(name) — first/last initials for letter-mark fallback
_avatar_gradient_for(uid) — deterministic per-user color (8 gradients)
_lock_company_payload(env) — company name + tagline + logo URL block
Endpoint /fp/tablet/tiles now returns:
{ok, company:{id,name,tagline,logo_url,has_logo,initials},
tiles:[{user_id, name, initials, avatar_url, has_photo,
avatar_gradient, is_clocked_in, has_pin}, ...]}
Tagline reuses res.company.report_header (the existing invoice-letterhead
field) — no new model field. Falls back to 'Shop Floor Terminal' when
empty.
10 tests pass (initials edge cases, gradient determinism, payload shape).
The 'tagline matches input string' assertion was intentionally NOT added

auto-wrapping that makes such an equality test brittle.
