Krzysztof Rudnicki c600760e71 Move billsplit Flutter app into the monorepo
billsplit was a standalone Flutter app in ~/Downloads with one commit and no
git remote — that directory was the only copy of its history.

Three things the move needed beyond copying the tree:

- The root .gitignore silently swallowed 32 of its files (*.png, *.ico,
  *.manifest). Ignored files do not error on `git add`, they just vanish, so
  this would have committed an app that cannot build. Added a trailing block
  of ! overrides plus .binary-allowlist (which did not exist yet) — the
  documented in-repo exception for binaries a build genuinely needs. The
  ../testsAndMisc_binaries/ symlink scheme does not apply: those directories
  are gone, and a symlinked PNG breaks a fresh clone.

- billsplit/.github/workflows/ci.yaml was inert once nested; GitHub only reads
  workflows at the repository root. Relocated with a working-directory and a
  billsplit/** path filter.

- The app's coverage gate moved to python_pkg/billsplit_coverage/ so every
  Python file stays under python_pkg/, and gained a test suite at 100% branch
  coverage as that location requires. billsplit/ now holds only Dart.

Also replaces the stock Flutter icon with a family icon from the shared
generator. The glyph is a filled silhouette because the family's 72px stroke
cannot carry a fine torn edge, and the split is an evenodd-cut perforation so
the holes stay transparent on the foreground and monochrome layers.
