fix(app): the app has its own icon instead of Flutter's
The launcher showed Flutter's logo: the project template's icons were
never replaced. tool/app_icons.py now makes every icon from the
kingfisher (assets/icon/halkyon_icon.png), through flutter_launcher_icons
v0.14.4 configured in the app's pubspec: Android's adaptive icon (the
kingfisher inset 16 % on white, for each launcher to cut to its shape)
and the square one before Android 8; iOS's, without transparency;
macOS's, the rounded tile on Apple's grid (824 of 1024 pixels); and
Windows', the rounded tile, its .ico with every size from 16 to 256
pixels (the tool writes only 256). It keeps the iOS project file as it
was, which the tool would break (flutter_launcher_icons issue 634), and
writes the snap's icon as tool/snap_icon.py did, which it replaces.

The Linux runner gives its window the bundled icon too, for desktops
that don't take it from the desktop file.

# The Linux app as a Snap, built in LXD on a developer's machine, in the repository
# root:
#
# snapcraft pack
#
# It builds what is committed (the source is this repository's HEAD), never the
# working tree with its build caches, and always for learn.halkyon.eu. Flutter is
# pinned like the local and CI one (FLUTTER_VERSION in .forgejo/workflows/ci.yaml):
# snapcraft's own Flutter plugin can only take a channel and can't pass
# --dart-define, so the build is spelled out below.

summary: Learn with flashcards, studied offline and synced between your devices
description: |
Halkyon Learn is a spaced-repetition learning app: studysets of flashcards with
rich text, notes, learning paths and PDFs, reviewed on an FSRS schedule. It works
offline and syncs between your devices.
It starts with an anonymous account; signing in with GitHub later keeps
everything. It connects to learn.halkyon.eu, the project's instance.
