Fix auth.json decoding for mixed provider schemas

[kargnas]

Addresses #64.

Problem

OpenCode Bar reads OpenCode's auth.json and decodes it into OpenCodeAuth.
If any single provider entry has an unexpected schema (different object shape, string instead of object, numeric fields as strings, etc.), decoding fails for the entire file. This shows up as [auth.json] PARSE FAILED even when the file exists and other providers are configured.

Root Cause

OpenCodeAuth decoding was strict: a decoding error for one key (for example openai or openrouter) threw out the whole OpenCodeAuth decode.

Fix

• Decode each top-level provider entry lossily (ignore per-key decode failures instead of failing the whole file).
• Make OAuth decoding more tolerant:
  • expires accepts Int64, Int, Double, or String.
  • accountId accepts a String or a number.
• Make API-key decoding more tolerant:
  • provider entries can be a raw string value.
  • accept common key field names: key, access, token, apiKey, value.
• Add unit tests for the lossy decoding behavior.

Notes

• Updated remaining non-English documentation/comments in touched areas to comply with the repo language policy.

Checks

• make lint
• xcodebuild build -scheme CopilotMonitor -configuration Debug
• xcodebuild build -scheme CopilotMonitor -configuration Release

Summary

• auth.json lossy 디코딩 때문에 스키마가 완전히 깨진 파일도 "성공"으로 처리되어 이후 경로 fallback이 막힐 수 있음. 아래 inline 제안처럼 최소 1개 유효 토큰 없으면 디코딩 실패로 처리하는 게 안전함.
• 나머지 변경(영문화, 테스트 추가)은 별도 이슈 없음.

CI/CD Status

• CI: 진행 중 (CI). Lint/Test/Build는 성공.

Local Verification

• npm install
• make lint-actions
• 미실행: SwiftLint/빌드/테스트 (Xcode 프로젝트/Package.swift 미확인)
