[BUG] app: Incorrect language name strings when using Thai language

[alexyaroshuk]

Bug:

In packages/app/src/i18n/th.ts, the language name strings (e.g., language.en, language.zh, language.de) were translated into Thai, but they should be static (same across all localization files).

What happened?

The Thai localization file contained translated language names:

• "language.en": "อังกฤษ" (should be "English")
• "language.zh": "จีนตัวย่อ" (should be "简体中文")
• "language.de": "เยอรมัน" (should be "Deutsch")
  Etc.

While all other localization files (en.ts, de.ts, ar.ts, br.ts, etc.) use static values that are consistent across languages.

OpenCode version

v1.1.48

Steps to reproduce

1. Change language to Thai in settings
2. Observe that all languages now are in thai

This issue might be a duplicate of existing issues. Please check:

• [FEATURE]: i18n add thai language support to desktop app #10810: Thai language support was added as a feature, this issue appears to be a bug fix related to that implementation
• zh: minor consistency issues (MCPs/LSPs plural, PDF casing, unit spacing) #10838: Similar localization consistency issues found in Chinese (zh.ts) file
• zh: punctuation/symbols in translations use ASCII style (?/:/() etc.) #10837: Related localization file issues with translations in non-English localization files

The pattern of language name strings needing to be static across all localization files is similar to the consistency issues found in #10838 and #10837.

Feel free to ignore if this is specific to a different aspect.
