Map tab: when UAT has no local data, shows a "Sincronizează terenuri,
clădiri și intravilan" button that triggers background base sync.
Sync background (base mode): now also syncs LIMITE_INTRAV_DYNAMIC layer
(intravilan boundaries) alongside TERENURI_ACTIVE + CLADIRI_ACTIVE.
Non-critical — if intravilan fails, the rest continues.
Also fixed remaining \u2192 unicode escapes in export/layers/epay tabs.

The \u0103, \u00ee etc. escape sequences were rendering literally in JSX
text nodes instead of displaying ă, î, ț, ș characters.
