Use Craft Application's Linter Service
Metadata
Current evaluation
Triaged refactor to replace Snapcraft's bespoke linter runner and reporting with Craft Application's LinterService; the prerequisite is merged, but migration remains unimplemented.
Suggested action: keep open
Reason: The issue is triaged as a refactor and defines three clear migration requirements. The current code still implements its own Linter base and run_linters/report flow across the lint command, lifecycle, and packaging service; craft-application#782 is now available through PR #907 and commit a76bcaa6, but no corresponding Snapcraft implementation exists.

Issue body
### Check existing issues
- [x] I've verified that this request isn't described by any existing issues.
### Request
Migrate to the Linter Service as implemented at https://github.com/canonical/craft-application/issues/782
* All linters are implementations of the Craft Application class
* The lint command uses the LinterService
* Any other uses of linters use the LinterService
### The problem it solves
Snapcraft and Charmcraft lint snaps and charms respectively at the end of the lifecycle.
These linters don’t share common code and don’t have a similar UX. Additionally, there isn’t a way to add linters to other *craft apps without significant code duplication.
Supersedes #5542
