resolve_runtime_provider returns the bare billing class 'custom' for every
named providers:/custom_providers: entry; the configured id only survives in
requested_provider. All three fallback resolvers (gateway, TUI/desktop, cron)
persisted runtime['provider'] as the agent identity, so an automatic fallback
labeled the session 'custom' in the UI and billing rows, while a manual
/model switch to the same provider showed the configured name.
New shared helper hermes_cli.fallback_config.effective_runtime_provider()
upgrades the bare class back to the entry's configured identity (ad-hoc
provider: custom entries stay unchanged), applied at all three sites —
same class as the delegate_tool fix.
