[registry] Add application labels and update filtering mechanism (#1707)
This change is extracted from
- https://github.com/cozystack/cozystack/pull/1641

and reworked to work standalone

## What this PR does

This PR extracts changes from the
https://github.com/cozystack/cozystack/pull/1641. It adds application
metadata labels to HelmReleases and updates the filtering mechanism to
use labels instead of chart/sourceRef matching.

Changes:
- Add three application metadata labels
(`apps.cozystack.io/application.kind`,
`apps.cozystack.io/application.group`,
`apps.cozystack.io/application.name`) when creating/updating HelmRelease
via Cozystack-API
- Replace `shouldIncludeHelmRelease` filtering with label-based
filtering in Get, List, and Update methods
- Always add kind and group label requirements in List for precise
filtering
- Update CozystackResourceDefinitionController to watch only
HelmReleases with `cozystack.io/ui=true` label
- Update LineageControllerWebhook to extract metadata directly from
HelmRelease labels instead of using chart mapping configuration
- Add functionality to update HelmRelease chart from
CozystackResourceDefinition using label selectors

## Summary by CodeRabbit

* **New Features**
* Added application metadata labels (kind, group, name) and exported
label keys for HelmRelease identification.
* New reconciler keeps HelmRelease charts in sync with application CRDs.

* **Refactor**
* Mapping, listing and selection moved to label-driven logic;
reconciliation responsibilities split so core reconciler focuses on
restart/debounce while a separate reconciler updates HelmReleases.

* **Chores**
* Migration script to backfill application labels on existing
HelmReleases.
