docs: audit and update all markdown files to reflect current progress

Phase 2 (WebDAV sync) and Phase 3 (GUI MVP) are complete but docs still
showed them as in-progress. Phase 4 Android steps 1-4 are done. Windows
MSI packaging was added. Multiple doc inaccuracies fixed: missing Error
variants, stale struct definitions, wrong filenames in directory trees.
