WebDAV connection settings were never part of the bundled settings
replica, so the "Credentials" sync toggle had no effect on them and
users had to re-enter their WebDAV server, username, and password on
every device.
Add webdav.serverUrl / username / password / rootPath to
SETTINGS_WHITELIST and gate username / password behind
SETTINGS_ENCRYPTED_FIELDS, matching how KOSync / Readwise / Hardcover
credentials are handled. Per-device bookkeeping (enabled, deviceId,
lastSyncedAt, sync sub-toggles) stays local, mirroring KOSync which
syncs credentials but not its enabled flag: a fresh device pre-fills
the connect form and the user clicks Connect.
Also add a webdav deep-merge case to mergeSettings. Without it the
top-level shallow merge on pull would replace the whole webdav object
with the four-field patch and wipe the local per-device fields.
Update the credentials category description to mention WebDAV and
migrate the i18n key across all locales.
