Khalid Abdi fb9fa299c9 frontend: RTL sidebar arrow placement + reverse-geocode clinic location
- Arabic RTL: stack the collapse arrow/bell above the nav icons instead of
  pinning them to the opposite edge; mirror the panel-toggle glyph; flip the
  notifications popover to open toward the content side.
- "Use my current location" now reverse-geocodes (OpenStreetMap Nominatim) to
  fill address/city/country, not just latitude/longitude, with a graceful
  coordinates-only fallback. New settings.location.geoPartial key in all 5 locales.

// Reverse geocoding via OpenStreetMap Nominatim. Used by the clinic-location
// settings so "Use my current location" can fill the address/city/country
// fields, not just the raw coordinates.
//
// Nominatim's usage policy asks for a descriptive User-Agent/Referer and low
// request volumes — this is only hit on an explicit button click, so occasional
// lookups are well within the acceptable-use limits.
