feat(shopfloor): per-user 7-day tablet event smart button

Owner-only smart button on res.users form. Click opens the audit log
filtered to that user (both user_id and attempted_user_id, so
failed unlock attempts against a tile show up too).

Compute is non-stored: search_count on the audit model per user on
demand. Sudo'd because the audit model has Owner-only ACL — the
compute fires for the form-viewing user (Owner) who would see the
results anyway via the menu.
