fix(fallbacks): allow free-form dest entries for external servers (#4748)

Since v3.1.0 every fallback row had to reference a panel inbound via childId, so rows with only a free-form dest (e.g. 8080 or 127.0.0.1:8080 to an external Nginx) were silently dropped at three layers: the frontend save filter, the backend SetByMaster guard, and BuildFallbacksJSON. A row is now valid when it has a child OR an explicit dest; self-references normalize to childId 0, and BuildFallbacksJSON prefers an explicit dest (also fixing rows whose child was deleted). UI gains allowClear on the child picker; help text updated across all locales. Verified end-to-end in Docker: a free-form dest fallback now persists and is injected into the live xray config. Refs #4554, #4639.
