feat(panel): build-before-bind + socks5 fixed node account (items 20+21)

Item 20: drop the zero-client deploy gate in ValidateNodeDeploy for
all protocols, stop RebuildNode from auto-removing a node whose
bindings reach zero, and let server/heartbeat reconciliation rebuild
zero-client nodes like any other. Nodes are built and deployed first;
bindings can be added and removed freely.

Item 21: socks5-auth nodes carry one node-level fixed account
(node.socksUser/socksPassword, minted at creation or by the store-load
migration MigrateSocksNodeCredentials, idempotent). The sing-box
inbound's only user is that pair regardless of bindings; subscription
links for every bound customer carry the same pair. The generated
username avoids the ng: prefix so the agent never attributes the
account's traffic to a customer — it stays on the node's inbound
counters. Edit form shows both fields (copyable) for socks nodes;
NormalizeNode validates operator-supplied usernames.
