ci: group cloud, desktop, mobile in one release workflow (#12802)

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit

- **New Features**
- Introduced new workflows for preparing releases, cloud deployment, and
coordinated multi-platform releases with manual approval for stable
Docker images.
- Added a reusable action to output app version, Git hash, and build
type for consistent release metadata.

- **Refactor**
- Simplified and unified input handling across workflows, requiring
explicit version and build metadata inputs.
- Updated release workflows (desktop, mobile, cloud) to use direct
inputs instead of deriving values internally.

- **Chores**
- Removed several legacy and redundant workflows, including automatic
deployment, release, label checking, auto-assign, and Helm chart
publishing.
- Deleted jobs and workflows related to self-hosted image builds, mobile
app test builds, and previous deployment processes.
