refactor(names): agent resolution + one error type

Adopt the simplexmq names rework (PR #7045): name resolution is now
owned by the agent (resolveSimplexName picks a names-role server), so
the chat-side iteration is removed - delete ResolveError,
iterateResolvers, resolveOnUserServers, enabledSMPServersForUser and
resolveErrorToChatError.

One error type: resolver/agent failures flow through ChatErrorAgent;
remove the CEvtSimplexName* events, SimplexNameVerifyFailReason,
SimplexNameConflictEntity and CESimplexNameResolverUnavailable.
APIVerifySimplexName returns CRSimplexNameVerified (verified::Bool),
mirroring CRConnectionVerified. connectPlan handles the name target
directly; updateProfile WithConflict aliases collapsed into the plain
functions.

Add the per-operator "names" SMP server role (migration
20260612_smp_role_names, official operator on by default) feeding
ServerRoles.names -> UserServers.nameSrvs.

Bump simplexmq pin to ce69adfd and regenerate sha256map.nix.

-Verify a contact's or group's claimed SimpleX name by RSLV-resolving the claim and comparing the resolved link to the peer's stored connection link. Synchronously returns `CRCmdOk`; the verification outcome is delivered asynchronously via [CEvtSimplexNameVerified](./EVENTS.md#cevtsimplexnameverified) or [CEvtSimplexNameVerifyFailed](./EVENTS.md#cevtsimplexnameverifyfailed).
+Verify a contact's or group's claimed SimpleX name by RSLV-resolving the claim and comparing the resolved link to the peer's stored connection link. Returns `CRSimplexNameVerified` with a boolean `verified` (a match also writes the verification timestamp); resolver / agent failures are reported as `CRChatCmdError`.

-### SimplexNameConflict
-
-A peer's profile update claimed a SimpleX name (`#name.simplex` / `@name.simplex`) that was already held locally by another contact or group. The displaced row's `simplex_name` is set to NULL and the claim moves to the newer row; this event surfaces the displacement so the bot can warn the user about a possible impersonation.

-
-RSLV verification of a contact's or group's SimpleX name claim succeeded: the resolved link matches the peer's stored connection link and `simplex_name_verified_at` has been written. Emitted asynchronously after [APIVerifySimplexName](./COMMANDS.md#apiverifysimplexname).

-RSLV verification of a SimpleX name claim did not succeed. `reason` indicates the cause: `SNVFLinkMismatch` (resolved link does not match stored link), `SNVFNameNotRegistered` (no on-chain record exists), or `SNVFResolverError` (transport / proxy failure, with the agent error inline). The `simplex_name` claim is **not** cleared. Emitted asynchronously after [APIVerifySimplexName](./COMMANDS.md#apiverifysimplexname).

-### SimplexNameUnverified
-
-A peer's incoming profile update (XInfo / XGrpInfo) carries a SimpleX name claim that the user has not yet verified — i.e. `simplex_name_verified_at` is NULL. Bots / UI may surface an unverified indicator next to the contact / group name; the user can clear it by invoking [APIVerifySimplexName](./COMMANDS.md#apiverifysimplexname).
