Add zh-Hant (Traditional Chinese) translations for dialog, groups, validation

Coverage improvements (all reach 100%):
- components/dialog.json:  50% → 100% (+46 keys, +9 manual plural-one)
- config/groups.json:        0% → 100% (+25 keys)
- config/validation.json:    0% → 100% (+22 keys)

Total: +93 net (after obsolete cleanup). Overall zh-Hant coverage now ~47%.

Translation approach (same pipeline as #23224 / #23225): OpenCC s2twp +
Taiwan MS-style dictionary + manual review. New AI-review patches added
to the dictionary in this batch:
- 訪問→存取 (access, MS style)
- 許可權→權限 (permission, Taiwan convention)

Also manually corrected 4 keys in config/validation.json where zh-CN had
mistranslated "role" as "功能" (feature) — corrected to "角色" (role),
and rewrote dialog.json shareTimestamp description for clarity.

Removed 1 obsolete key (streaming.restreaming.desc.readTheDocumentation)
that no longer exists in the en locale.
