webdav_patch.hurl and nc_webdav_patch.hurl existed with real coverage since the original PATCH commits but were never added to tests/api/run.sh, so just api-test/CI silently skipped them. Wire both in, fix nc_webdav_patch.hurl's header-after-[BasicAuth] ordering bug that meant it had never actually passed, and add two new consistency-focused files chaining PATCH operations with cross-protocol/cross-surface verification: - webdav_patch_consistency.hurl: chained overwrites with ETag-change checks, GET/HEAD/PROPFIND cross-protocol agreement, quota-507 leaving the file byte-for-byte unchanged, direct_put_max_bytes prefix/suffix regression coverage. - nc_webdav_patch_consistency.hurl: Editor/Viewer/Outsider permission matrix, cross-surface lock interop, quota-507 via the NC surface. Running these surfaced two real bugs in the NC PATCH handler, both fixed here: - The write step mapped every error (including a legitimate anti-enum permission denial) to a raw 500 instead of AppError::from(e), unlike the plain surface. A Viewer without Update permission got a 500 leak instead of the expected 404. - nc_to_internal_path() didn't strip the leading '/' that chroot.path carries from StoragePath::to_string(), so a LOCK taken via /webdav/ silently failed to block PATCH via /remote.php/dav/ on the same file — the exact-string lock-store lookup never matched. Added a regression unit test.
