🧠 fix: Handle Reasoning Chunk Edge Cases

[danny-avila]

Closes #5678
Closes #5790

Summary

• Refactored reasoning parsing in OpenAIClient by extracting and processing tokens robustly, ensuring accurate assembly of streaming tokens.
• Adjusted reasoning content handling in ContentParts, MessageContent, and the Reasoning component to trim and display output correctly.
• Upgraded the "@librechat/agents" dependency in api/package.json from "^2.0.3" to "^2.0.4" to handle think tags found in larger chunks.

Other Changes

• Updated Vite in client/package.json from "^5.4.14" to "^6.1.0" to leverage the latest build improvements.
• Refined mobile styling in TemporaryChat and SelectDropDownPop by adjusting layout, spacing, and truncation for a more polished interface.
