fix(accounts): unlock parent provider when enabling rows

Make individual Debrid-Link and Mega-Debrid switches express an explicit enabled target. Enabling a row now clears both its own disabled identifier and the effective provider lock; Mega-Debrid also re-enables the selected API or web mode.

Keep row-level disabling scoped to the selected account, align the legacy key view with the effective provider state, and cover the provider-plus-account lock combination with a regression test.
