fix(inbox): make Discuss question input a resizable textarea

[andrewm4894]

Problem

The optional "Discuss" question input on inbox report details is a single-line TextField cramped inside a 320px popover. Users have started using Discuss to ask longer questions (and even series of questions) and the tiny one-liner is awkward — most of what they type is hidden off-screen.

Changes

• Swap the TextField.Root for a Radix TextArea so it's multi-line by default.
• Set rows={5} for a noticeably taller default height.
• resize="vertical" so users can drag from the bottom-right to make it bigger when they want to type more.
• Widen the popover from 320px to 420px so the textarea isn't squeezed.
• Add Cmd/Ctrl+Enter to submit (with a small Kbd hint) since Enter now inserts a newline in the textarea.

How did you test this?

• pnpm --filter code typecheck passes.
• biome check on the changed file passes.
• Did not manually run the Electron app in this environment, so the UI/drag behavior has not been visually verified — worth a quick local check before merge.

apps/code/src/renderer/features/inbox/components/detail/ReportDetailPane.tsx:577-579
The keyboard hint always shows the Mac `⌘` symbol, but non-Mac users must press Ctrl+Enter. The existing "Create PR" shortcut right below in the same file already uses `isMac` from `@utils/platform` to render the correct label per platform — this hint should do the same.

                    <Text size="1" color="gray">
                      <Kbd>{isMac ? "⌘" : "Ctrl"}</Kbd> <Kbd>↵</Kbd> to send
                    </Text>
