feat(ui): mobile-first redesign — compact hero, inline submit button, map-first with collapsible list

- Hero: remove full-width mobile submit, add inline "Go" button next to locate
- Prediction cards: tighter mobile padding (px-3 py-3)
- Search filters: right-aligned toolbar, remove "X stations found" count and map toggle
- Map: initialize view immediately to avoid tile wiggle, skip recenter on fresh init
- Station list: hidden by default, toggled via "Stations {count}" pill above map
- Typography: hide desktop h1 on mobile, scale down section headings and spacing
- Footer: remove uppercase styling from headings and copyright line
- Filter popover: auto-close on fuel/radius/sort/brand selection

fix(llm): retry submit_overlay when events_cited is missing, extend Fuel Finder timeout with retries

- LlmOverlayService: add `minItems: 1` to events_cited schema, detect missing citations
  in submit response, inject tool_result error and retry once with explicit prompt
- Log full raw_result context when no verified citations, capturing direction/confidence/reasoning
- FuelPriceService: add 3×1s retry with 60s timeout to batch price requests (was 30s no retry)
- Tests: cover successful retry recovery and rejection when retry also omits citations
