### Motivation
- Ensure share URLs fully capture map layer state by including every key
from the `MapLayers` type (geopolitical and tech layers).
- Keep `parseMapUrlState` and `buildMapUrl` consistent so both parsing
and serialization cover the same complete set of layers.

### Description
- Expanded the `LAYER_KEYS` array in `src/utils/urlState.ts` to include
`ais`, `protests`, `military`, `spaceports`, `minerals`, `startupHubs`,
`cloudRegions`, `accelerators`, `techHQs`, and `techEvents` so it
matches `MapLayers`.
- `parseMapUrlState` continues to use `LAYER_KEYS` to populate a
`MapLayers` object from the `layers` query param, now covering the full
set.
- `buildMapUrl` uses `LAYER_KEYS` to serialize active layers into the
`layers` query param, ensuring all layer flags are represented in share
URLs.
- Change is contained to `src/utils/urlState.ts` and committed.

### Testing
- No automated tests were run for this change.
