feat(hints): auto-inject on every main page via URL→key registry

Registry now covers ~50 hints across Service, CRM, Depozit, Finanțe,
Admin, Marketing, Analiză, Shop. Every main tenant page has an entry.

New Hints::forPath(\$path) does str_starts_with matching against a
curated URL prefix map. First match wins so specific paths (e.g.
/work-orders/create) beat broader ones (/work-orders).

A single render hook on PAGE_HEADER_ACTIONS_BEFORE looks up the
current request path and, if it matches, renders a "?" icon next to
the page header actions. Blades that already have <x-hint> tags
embedded (WO dashboard, Calendar, Pipeline, Excel wizard) keep those
on top of the auto-injected header hint.

Net effect: users see "?" icons everywhere in the panel now, and
adding coverage for a new page is a 2-line change (registry entry +
one URL prefix in forPath).
