chore(build): bump flatpak-sources plugin to 0.1.7, drop Isolated Projects workaround

[jamesarich]

Why

org.meshtastic.flatpak.sources.settings was pinned at 0.1.5 because it read
Gradle.extensions in a way Isolated Projects forbids — this repo runs with
Isolated Projects on by default (org.gradle.isolated-projects=true), so
every flatpak-sources generation call had to disable IP + config cache, and
the plugin itself was gated behind an opt-in property in
settings.gradle.kts. Upstream 0.1.7
(meshtastic/gradle-flatpak-sources#36)
fixes the incompatibility by sharing state via a BuildService instead.

Changes

• 🛠️ Refactoring & Architecture
  • Bump org.meshtastic.flatpak.sources.settings 0.1.5 → 0.1.7 and apply it
    unconditionally again (removed the apply false + opt-in-property gate).
  • Drop -Dorg.gradle.isolated-projects=false --no-configuration-cache -Pmeshtastic.flatpakSources=true from the four call sites that carried
    it: verify-flatpak.yml, release.yml, reusable-check.yml,
    verify.sh.

Testing Performed

Verified end-to-end, not just compiled: ran the real
:desktopApp:packageUberJarForCurrentOS :captureFlatpakSources pipeline
with Isolated Projects left on (this repo's default) and none of the
removed workaround flags — 189 tasks, zero IP/config-cache violations,
flatpak-sources.json emitted with 2808 captured URLs.
