fix: de-flake import deep-link cURL auto-scan smoke test (#10555)

## Background

The `value-bearing curl param` smoke test failed intermittently on CI
(run 35832135624, shard 3/6, both retries) while passing on isolated
reruns and in dev mode.

Repro: `npm run test:smoke:build -- --project=Smoke --grep "value-bearing curl param" --repeat-each=20 --workers=4`
→ ~25% first-attempt failure rate.

## Root cause

A value-bearing deep link auto-scans, and the scan result replaces the
pre-scan form within milliseconds of the modal opening. The assertion
`getByText('http://insomnia.rest/')` could only match the transient
pre-scan state — the raw cURL in the textarea's initial text content —
so the test raced against scan completion and lost whenever the scan
landed before the first assertion poll (fast in build mode on CI).

The stable post-scan state never contained the URL text at all: the
scan-results table renders
`{importerSign} resources to be imported from {oriFileName}:`, and the
cURL scan source sets no `oriFileName`, producing the dangling-colon
label "cURL resources to be imported from :".

## Changes

- `import-modal/shared.tsx` — omit the `from {oriFileName}` clause when
  a scan result has no source name (cURL deep-link scan). Sources with a
  real name (uri, file, clipboard, mcp) keep the existing wording.
- `import-deep-link.test.ts` — assert the stable post-scan state
  ("cURL resources to be imported:" and "1 Request") instead of the
  transient pre-scan form; renamed the test accordingly.

## Verification

- Fixed test: 20/20 passed under the same build-mode + parallel-load
  conditions that produced 5/20 flaky before the fix.
- `import deep links` suite: 3/3 passed in build mode.
