update_file_streaming_with_perms (the method behind every WebDAV/
NextCloud/WOPI PUT) never called the storage-usage-delta hook, so
drives.used_bytes and the RFC 4331 quota-used-bytes property never
reflected content written via WebDAV — only the REST multipart
upload path bumped usage. Extract apply_storage_usage_delta() from
maybe_update_storage_usage() and wire it into both branches: the
overwrite path applies new_size - old_size, the create path applies
the full size.
Also fixes the two RFC 4331 hurl tests that caught this:
nc_webdav_quota_properties.hurl had a Hurl parse error ([BasicAuth]
section keys can't mix literal+template, so the {user}~{folder}
composite marker is now pre-resolved via [Options] variable: before
being referenced as a single template), and both quota-properties
tests now retry the post-upload PROPFIND (matching the existing
drive_quota.hurl/user_envelope_quota.hurl pattern) since the delta
is applied fire-and-forget on a background task.
