The Port-with-Fallback inbound (commit 62fd9f9d) was confusing as a
standalone protocol — fallbacks belong on a regular VLESS/Trojan TCP-TLS
inbound, the way Xray models them natively. Rip out the entire feature
cleanly (no migration needed since it was never released): protocol
constant, fallback children DB table, FallbackService, 2 API endpoints,
all UI rows, related translations and api-docs. A native fallback flow
attached to VLESS/Trojan TCP-TLS/Reality will land in a follow-up commit.
