build(flatpak): Refactor build configuration to support offline build-logic resolution

- Replace basic `settings.gradle.kts` appending with a Python-based rewriting script for both root and `build-logic` settings.
- Configure `pluginManagement` and `dependencyResolutionManagement` to strictly use the local offline repository for all project modules.
- Explicitly include `build-logic` and configure its version catalog resolution from `gradle/libs.versions.toml`.
- Update build source from a remote Git tag to the local directory for development builds.
- Remove the `--offline` flag from the Gradle execution as network isolation is handled by the Flatpak sandbox.
- Update comments to clarify Flathub submission requirements for source types.
