feat(geoportal-v2): manual fetch flag + friendlier pool-exhausted error

Two operational gaps observed after PR3 deep-enrich rollout:

1. Raw \"Eroare: no_available_account\" surfaced when the eTerra
   account pool hit its hourly quota. Replace with a plain-language
   note ("Pool-ul ANCPI e temporar epuizat — încearcă peste câteva
   minute"). Same friendly treatment for the other common
   orchestrator errors: no_immovable_match, parcel_not_found,
   eterra_fetch_failed.

2. Marius wants the auto-trigger (fires on sparse-data load) and the
   explicit "Citește din ANCPI" button to be separable on the
   orchestrator side. Casual map browsing burns through the 500/h
   quota with auto-triggers; a working session that needs 20-30
   specific parcels shouldn't be starved.

   refreshFromAncpi now takes { manual?: boolean }. The button passes
   manual: true → request body includes manualOverride: true. The
   auto-trigger useEffect calls it with no argument (manual defaults
   to false). gis-api / orchestrator can later route manualOverride
   to a separate-quota bucket or skip the per-hour check entirely.
   Until then the flag is harmless (orchestrator ignores unknown
   fields).
