fix(docker): prevent bundler from loading dev/test gems in production builds

Containers were failing to start because Bundler was attempting to resolve
and load development/test gems even though they weren't installed (due to
`bundle install --without development test`). This occurred because Bundler
parses the entire Gemfile and tries to resolve all gem groups, regardless
of the --without flag.

Changes:
- Wrap dev/test gem groups in conditional `unless ENV['SKIP_DEV_GEMS']`
  to completely exclude them from Bundler's view during production builds
- Set `ENV SKIP_DEV_GEMS=1` in all Dockerfiles before bundle install
- Add explicit `gem "anycable", "~> 1.5"` to fix missing anycable RPC command
- Update deprecated platform syntax from `:mingw, :x64_mingw` to `:windows`
- Add `.bundle/` to .dockerignore to prevent local bundler config from
  overwriting Docker build config
- Make RAILS_ENV configurable via .env with production as default
  (`RAILS_ENV: "${RAILS_ENV:-production}"` in compose.yaml)

The conditional logic preserves local development functionality - when
SKIP_DEV_GEMS is not set, dev/test gems are defined and installed normally.

Fixes: Container startup failures with "Could not find gem 'byebug' in
locally installed gems" error despite using --without development test
