fix(tty): filter terminal probes by channel #40356

Problem:
Terminal probes sent with `nvim_ui_send()` can reach more than one stdout TTY
UI. Probes with a known TTY UI owner should not accept `TermResponse`s from
unrelated UI channels. 

Solution:
Thread the existing `chan` filter through owned terminal probes. This covers
startup/attach background detection, fallback truecolor detection, and
`vim.tty.query()` forwarding opts to `vim.tty.request()`.

Note: Not every terminal escape path is updated here. I only passed `chan` when
the caller already knows which TTY UI owns the probe. For example, this does
not include:
- (Followup) OSC 52 (system clipboard) detection. It needs to capture the
  `UIEnter` channel. Adding `{ chan = ... }` only to the nested query would be
  half a fix.
- OSC 52 _paste_ is left global because the provider callback does not have
  a UI channel (paste is invoked without a ui channel/tty ui object).
