✨ feat(devin): recognize Devin credentials and model namespace

[seakee]

Summary

Introduce foundational Devin provider support to CPA Manager Plus. This initial phase establishes Devin identity, official light/dark credential iconography and theme colors, and namespace-first recognition for devin/* models while preserving canonical model identifiers.

Scope

• Frontend panel
• Manager Server
• CPA panel mode
• Full Docker mode
• Native packages / release
• Docs / Wiki
• CI / build / tooling

Changes

• Add 'devin' to AuthFileType in apps/web/src/types/authFile.ts.
• Add official Devin light and dark SVG icons (devin.svg, devin-dark.svg).
• Register Devin brand theme colors and icon mapping in apps/web/src/features/authFiles/constants.ts.
• Implement namespace-first categorization for devin/* models in apps/web/src/utils/models.ts so underlying models (e.g. devin/gpt-5, devin/claude-sonnet) are correctly categorized as Devin while preserving full IDs.
• Register Devin icon mapping in System Models view (SystemPage.tsx).
• Add localized filter labels (filter_devin: "Devin") across en, ru, zh-CN, and zh-TW.
• Add unit tests for model classification, credential metadata, and account provider tabs.

User Impact

Devin credentials and devin/* models are now recognized with the official Devin brand identity and icons rather than Unknown or misclassified into underlying model families (GPT, Claude, Gemini, Grok, DeepSeek).

Compatibility / Runtime Notes

• CPA panel mode: Fully compatible; static icon and theme assets are bundled into standalone dist/index.html.
• Manager Server mode: Fully compatible; uses existing frontend credential normalization.
• Full Docker / native packages: N/A (frontend presentation change only).

Data / Security Notes

N/A. No changes to credential storage, keys, or sensitive data handling.

Risk / Rollback

Risk level: Low

Rollback notes: Can be cleanly reverted via git revert without schema or data migration impacts.

Docs

• README / README_CN updated for user-visible capabilities
• Matching docs manual and navigation updated
• Demo fixtures, screenshots, and deep links reviewed
• Release notes needed
• Not needed — explanation included below

Docs decision: Initial phase establishes internal frontend identity and model classification; comprehensive docs will be updated when the full Devin provider feature set (OAuth, quota) is completed.
