LmxProxy is no longer needed. Moved the entire lmxproxy/ workspace, DCL
adapter files, and related docs to deprecated/. Removed LmxProxy registration
from DataConnectionFactory, project reference from DCL, protocol option from
UI, and cleaned up all requirement docs.
LmxFakeProxy is no longer needed now that two real LmxProxy v2 instances
are available for testing. Added remote test infra section to test_infra.md
documenting the windev instances. Removed tagsim (never committed).
Move all CRUD create/edit forms from inline on list pages to dedicated form pages
with back-button navigation and post-save redirect. Add Playwright Docker container
(browser server on port 3000) with 25 passing E2E tests covering login, navigation,
and site CRUD workflows. Add POST /auth/token endpoint for clean JWT retrieval.
Organize documentation by moving requirements (HighLevelReqs, Component-*,
lmxproxy_protocol) to docs/requirements/ and test infrastructure docs to
docs/test_infra/. Updates all cross-references in README, CLAUDE.md,
infra/README, component docs, and 23 plan files.
