Aleksey Orekhovsky ee459b7410 Reduce Docker image size by refactoring map loading (#1621)
## Description:

This PR implements a major refactoring of how map data is stored and
loaded, as described in #1242. Previously, map data (`.bin` files) was
bundled directly into the client-side JavaScript by Webpack using
`binary-loader`. This approach led to data duplication and increased
bundle/image sizes.

This refactoring changes the strategy entirely:
- `GameMapLoader` interface has been introduced to decouple the map
loading mechanism from the components that use it.
- New `FetchGameMapLoader` implementation loads map data by fetching it
from static server endpoint.
- Webpack configuration and `Dockerfile` have been updated to serve the
map files as static assets and to remove the source `resources/maps`
directory from the final image, thus eliminating data duplication.

This leads to several key improvements:
- Docker image size is reduced from ~750 MB to ~600 MB.
- Build time is decreased. On my local machine, the docker image build
time went from 48s to 43s.
Most of this speed-up comes from faster Webpack builds (reduced from 16s
to 11s), as it no longer needs to process large binary files. This
performance gain will be noticeable for all developers during local
development, not just in the CI workflow.
