fix(i18n): align desktop zh/zh-hant allowSession wording with CLI

[dx2102]

What does this PR do?

Improves the zh/zh-hant translation of the desktop "Allow this session" button to match the CLI's existing wording.

English sources

# apps/desktop/src/i18n/en.ts:2300   (button label)
allowSession: 'Allow this session'

# locales/en.yaml:22                  (confirmation line)
allowed_session: "      ✓ Allowed for this session"

The intended reading of "Allow this session" is "allow (this command) for this session", not "allow the session itself". The session is the scope of the allow, not the object being allowed. The CLI's "Allowed for this session" makes the same scope reading explicit by keeping the preposition.

Current Chinese (desktop) — mistranslates the scope as the object

• zh.ts: 允许本会话 (reads as "allow the session itself")
• zh-hant.ts: 允許本工作階段 (same ambiguity)

CLI already ships the correct scope-adverbial wording

Key approval.allowed_session:

• zh.yaml: 本次会话内允许
• zh-hant.yaml: 本次工作階段內允許

This PR brings the desktop labels in line. Both surfaces (button vs. confirmation) describe the same scope; Chinese should express it uniformly. No behavior change.

Type of Change

• 🐛 Bug fix

Changes Made

• apps/desktop/src/i18n/zh.ts: allowSession → 本次会话内允许
• apps/desktop/src/i18n/zh-hant.ts: allowSession → 本次工作階段內允許

How to Test

Switch desktop to Simplified / Traditional Chinese, trigger an approval prompt, open the "▼" menu next to Run. The middle item now matches the CLI approval prompt.

Code Review Summary

Verdict: LGTM (reviewer's token is read-only — submitted as COMMENT instead of APPROVE; maintainer can formally approve).

Pure i18n string alignment — changes two catalog strings in apps/desktop/src/i18n/zh.ts and zh-hant.ts so the desktop button label allowSession matches the CLI's existing allowed_session scope-adverbial phrasing (本次会话内允许 / 本次工作階段內允許).

The diff is minimal and well-scoped: 2 lines changed across 2 files, no behavior change, no test surface needed for catalog strings. The PR description documents the rationale clearly (scope-as-adverbial reading) and the source-of-truth for the new wording (locales/en.yaml:22, locales/{zh,zh-hant}.yaml).

Looks good.
