chore(web): address Copilot review on #2130

Three findings, all valid on verification.

`onToggleConnection` and `onDisconnect` do not own every rejection, so a
bare `void` on them turns an ordinary Connect/Disconnect click into a
global unhandled rejection with nothing shown to the user. The toggle has
three escape paths outside its own try/catch — awaiting
`initialConfigSettledRef`, constructing the client via
`setupClientForServer`, and the already-connected disconnect branch,
whose `try/finally` runs `finalizeExplicitDisconnect()` and then lets a
failed transport close propagate — and `onDisconnect` is that same
`try/finally` on its own. Both are now terminated with a `.catch` that
toasts the failure.

The blanket comment claiming all seven wrappers own their failures was
wrong. The five command handlers (`onCallTool`, `onGetPrompt`,
`onReadResource`, `onCancelTask`, `onOpenApp`) do each end in a `catch`,
so `void` stays correct for them; the comment now splits the two groups
and says which is which.

Adds the two tests the review asked for, covering the rejected-close path
through both the toggle and the explicit Disconnect. Each fails against
the previous `void` code, so they pin the fix rather than merely passing.
The `InspectorView` double grows a `disconnect` button, since the
standalone `onDisconnect` was otherwise unreachable from it.

Also restores the `PropOverrides` doc example, which the scripted
regrouping had rewritten inside its own JSDoc into a triple-nested shape
that would not type-check if copied.
