fix(dbbrowser): rewrite saved queries for the Notes integer schema

Notes.RootBlogName/NoteBlogName/Type were replaced by RootBlogId/NoteBlogId/
TypeId (resolved via BlogNames and NoteTypes) back on 2026-08-07. The saved
DB Browser for SQLite queries in RERUN.sqbpro and TL.sqbpro still referenced
the old text columns and failed against the migrated TL.db.

Rewrote the 5 affected queries per TL.db.md's porting guide: Notes<->Blogs
joins go through Blogs.BlogId in one hop, Notes<->Posts joins route through
BlogNames (Posts has no BlogId), and type filters resolve through NoteTypes.
Verified read-only against the live TL.db -- all 5 execute without error.
