fix(rgi+portal): default sort desc by termen, fix overlaps, tooltip

RGI (both pages):
- Default sort: Termen descrescator (cel mai in viitor sus)

Portal map:
- Basemap switcher moved left (right-12) to avoid zoom controls overlap
- Selection toolbar moved up (bottom-8) to avoid attribution overlap
- Download button has title tooltip on mobile cards
