refactor(useChatWidget,useAvatarInfoWidget): reactive ownUserId + typed avatar-click-control

Two small modernization wins on the previously skip-motivated god-hooks.
Neither hook lends itself to the data/actions split, but both had
concrete imperative-style residue worth tidying:

== useChatWidget

Replace `const ownUserId = GetSessionDataManager()?.userId || -1;` with
`useUserDataSnapshot().userId`. The previous read happened at hook mount
and stayed pinned to whatever userId the manager held at that point —
a session change (re-login without page reload) would silently corrupt
the outgoing-translation owner check below. With the snapshot hook,
the value updates reactively via SESSION_DATA_UPDATED and the
useNitroEvent re-registration picks up the fresh ownUserId for every
incoming chat event.

== useAvatarInfoWidget

Two tidy points:

- CLICK_USER_DEBOUNCE_MS (the 120ms window during which a directional
  click suppresses the context menu) lifted from inside the hook body
  to a module-level const. It's never going to change at runtime and
  doesn't depend on hook state — keeping it inside meant it was
  redeclared on every render.

- The `(globalThis as any).__nitroAvatarClickControl` read replaced by
  a typed `getAvatarClickControl()` helper backed by a proper
  `NitroAvatarClickControl` interface. Same runtime behaviour; type
  channel no longer goes through `any`, and the symbol is documented
  in one place above the hook.

Public APIs of both hooks unchanged. Suite: 207/207.
