feat: implement map-specific localStorage and TALAS-Kabelstrecken dependency logic

- Add map-specific localStorage keys using URL parameters (m=mapId, u=userId)
- Implement kartenspezifische Sichtbarkeitseinstellungen per Map/User
- Fix localStorage priority over GisSystemStatic Allow values to preserve user settings
- Add bidirectional TALAS ↔ Kabelstrecken dependency logic:
  * Kabelstrecken aktiviert → TALAS automatisch aktiviert
  * TALAS deaktiviert → Kabelstrecken automatisch deaktiviert
- Update mapLayersSlice.js to respect existing localStorage values over system defaults
- Modify MapComponent.js to load map-specific visibility settings on mount
- Update MapLayersControlPanel.js with kartenspezifische localStorage handling
- Fix useDynamicDeviceLayers.js visibility logic (corrected boolean conditions)
- Update useAreaMarkersLayer.js for map-specific localStorage keys

BREAKING CHANGES:
- localStorage structure changed from "mapLayersVisibility" to "mapLayersVisibility_m{mapId}_u{userId}"
- User visibility preferences now have priority over GisSystemStatic Allow values
- TALAS and Kabelstrecken are now logically linked (dependency relationship)

This resolves issues with:
- Map switching losing visibility settings
- Browser reload overriding user preferences with system defaults
- Missing logical connection between TALAS stations and their cable routes
