feat(dbviewer): full-text-search toggle wired to FTS5 query API

New UseFullTextSearch transient UI bool flips DbViewer.Filter() between
the existing local page filter (default) and the FTS5 MATCH path across
the whole database. ImRaii.Disabled blocks the toggle while the bulk-insert
worker is still building the index; the HelpMarker swaps between two
hints, one for the indexing state and one for the phrase-match advisory
once the index is ready.

Three new HellionStrings entries cover EN + DE + the Designer accessor:
- DbViewer_FullTextToggle (label)
- DbViewer_FullTextToggle_Hint_Indexing (tooltip while indexing)
- DbViewer_FullTextToggle_Hint_PhraseMode (tooltip once ready, warns
  multi-word terms match as phrases and how to opt into raw MATCH syntax)

Filter() short-circuits to the local fallback if the toggle is on but
ftsReady has flipped back to false -- defensive against a mid-session
Dispose-and-reopen during indexing.

v1.4.8 H2 Sub-Task 4.4.
