test(web): refresh stale system-message session fixtures

Fourteen current Web v2 fixtures still store the system prompt in
request/header.system and omit system/message. The built Cordis owner
passes its five behavior assertions but fails persisted-session replay.
Refresh thirteen owning recorded scenarios and update the authored pwsh
seed input to carry the same system text as a message event.

Keep the lower branch's title-before-header order. Preserve all 90
user/model/tool messages and all 35 recorded Assistant streams, including
timing. Only the system event, header field removal, message identifiers,
and their sequence references differ. Frozen v0/v1, UI goldens, runtime,
and normalizers remain unchanged.

Evidence on macOS, base 8d66f7c917:
- pnpm install --frozen-lockfile && pnpm run build: passed.
- DSH_SNAPSHOT=replay pnpm exec vitest run --config vitest.web.config.ts apps/web/tests/cordis-tool-round.e2e.ts: before repair, persisted replay failed after 5 behavior tests passed.
- DSH_SNAPSHOT=refresh pnpm exec vitest run --config vitest.web.config.ts apps/web/tests/{approval-composer,cordis-tool-round,feedback-command,file-upload-round,replay-round-trip,lifecycle-chrome,live-interactions,permission-policy-context,ptc-round,question-composer,steering,turn-tail-actions,web-search-round}.e2e.ts: 13 files passed; 71 tests passed, 2 record-only tests skipped.
- PATH="/tmp/pwsh:$PATH" DSH_SNAPSHOT=refresh pnpm exec vitest run --config vitest.web.config.ts apps/web/tests/pwsh-terminal.e2e.ts: 2 tests passed with existing PowerShell 7.4.6.
- PATH="/tmp/pwsh:$PATH" DSH_SNAPSHOT=replay pnpm exec vitest run --config vitest.web.config.ts apps/web/tests/{approval-composer,cordis-tool-round,feedback-command,file-upload-round,replay-round-trip,lifecycle-chrome,live-interactions,permission-policy-context,ptc-round,pwsh-terminal,question-composer,steering,turn-tail-actions,web-search-round}.e2e.ts: 14 files passed; 73 tests passed, 2 record-only tests skipped (102.62s).
- Exact base/current JSON comparison: all 14 files equal base plus the system event, header.system removal and deterministic ID/sequence remapping.
- No current Web v2 request/header.system remains; git diff --check passed.
