WebUI: remember seeds/size filters

Mirror the desktop GUI "Remember filters" feature in the Web
interface. Previously the seeds and size search filters reset to
their defaults for every new search tab (resetFilters()), while
only the "Search in" mode persisted via ClientData.

Add a "Remember filters" checkbox to the search filter row. When
ticked, the seeds/size filter values (including size units) are
stored via ClientData and used to seed new search tabs; when
unticked, behaviour is unchanged. The stored values and checkbox
state persist across sessions, following the same ClientData
pattern already used for "search_in_filter".
