fix(chargers): surface missing saved connections

[frahlg]

When a charger kept the name of a removed or renamed driver, Settings showed it as a saved connection and validation gave no warning. Settings now marks the missing connection, keeps the warning after save, and clears it when the owner chooses a configured charger or removes the entry. The saved choice stays intact. An unseen OCPP identity remains unverified.

Setup validation now saves warnings even when it leaves the settings bytes unchanged, and binds those warnings to the reviewed draft revision. The diagnostic catalogue includes exact saved charger names and their binding status, plus the full-read workflow an assistant needs to check them.

Paired Cloud change: srcfl/ftw-cloud#41 (MCP guidance and diagnostic refusal handling).

Validation:

• Full make verify passed.
• All 857 web tests passed.
• Targeted config, onboarding and API race tests passed.
• Browser comparison used the real Settings scripts with a local fixture: the missing connection warns, choosing easee_cloud saves the new binding and removes the old option and warning; the narrow view has no horizontal overflow.

Fredrik reviewed the rendered UI and approved both paired merges on 19 October 2026. The local preview uses no private site data. Release, Cloud deployment and box installation remain separate steps.
