feat(agentnetwork): require identity echo on settings PUT, add guarded DELETE

Lands the review decision from #7085: PUT keeps the API-wide convention
of requiring every field. endpoint and proxy_address join the update
schema as required fields, compared against the stored row (trimmed,
case-folded) and rejected with 422 on mismatch. They are never written,
so the identity stays immutable while the request shape stays
conventional.

Because the identity is immutable, clients that model change-as-replace
(the Terraform provider's RequiresReplace) need a real delete. DELETE
/api/agent-network/settings now exists with two guards, both checked
under the row lock: no providers may exist for the account, and no
active proxy may declare the endpoint hostname as its cluster address.
Either refusal is a 412. The proxy guard checks the endpoint hostname
rather than the proxy address: for a dedicated pin they are equal, and
for a labeled pin the shared parent cluster being up says nothing about
this account once its providers are gone. Re-creating after a delete
allocates a fresh endpoint; the released hostname is not reserved.

+#### `connection_type` values
+
+Derived from the connection priority (`conntype.ConnPriority`) by `metricsConnType` in `client/internal/peer/conn.go`:
+
+| Value | Priority | Traffic is |
+|-------|----------|------------|
+| `ice_p2p` | `ICEP2P` | direct peer-to-peer |
+| `ice_turn` | `ICETurn` | relayed, through a TURN server |
+| `relay` | `Relay` | relayed, through a NetBird relay |
+| `unknown` | `None` or unrecognised | no active transport — **the sample is not pushed** |
+
+**Direct traffic is `ice_p2p` only.** `ice_turn` is relayed despite being negotiated by ICE, matching `Conn.isRelayed`.
+
+`None` means no transport is active: not established yet, or reset after a relay drop or a peer-state reset. Such a sample cannot be attributed to a transport, so `recordConnectionMetrics` drops it instead of pushing it — `unknown` therefore never appears in the bucket. Connection counts are counts of connections whose transport was known at sampling time.
+
+**Samples recorded before 0.77 used a single `ice` value** which covered `ICEP2P`, `ICETurn` *and* `None`, so historical `ice` samples overstate direct connections by an unknown amount and must not be compared with `ice_p2p`.
