Add interactive customer robot map

Solving issue #86
Customer Map Report

Added a new interactive robot map to the customer webapp home page.

Changes included:

• Created a new customer-map branch.
• Added the leaflet dependency for interactive maps.
• Replaced the original static/mock map display with a real Leaflet map.
• Connected the map to the existing robot data already used by the fleet cards.
• Updated demo robot coordinates to Spokane, WA.
• Centered the map around Spokane.
• Added OpenStreetMap street tiles so the map shows roads, street names, and surrounding locations.
• Added zoom controls and map panning.
• Added robot markers using the existing robot status colors:
• Available
• On delivery
• Charging
• Added marker tooltips showing robot ID and status.
• Added map attribution for OpenStreetMap.
• Added VITE_MAP_TILE_URL support so the tile provider can be swapped later if needed.
• The robot locations currently refresh every 5 seconds because the frontend polls /api/simulator/bots on that interval. When the simulator API is unavailable, the app falls back to Spokane demo robot data.

Verification completed:

npm.cmd run build
npm.cmd run lint

Browser check confirmed the map loads, shows street tiles, displays all 3 robot markers, and supports zooming.
