Fix UI text: Replace remaining "Codex" with "LLMX"

Updated user-facing strings throughout the TUI:

Slash commands:
- "instructions for Codex" → "instructions for LLMX"
- "ask Codex to undo" → "ask LLMX to undo"
- "exit Codex" → "exit LLMX"
- "what Codex can do" → "what LLMX can do"
- "log out of Codex" → "log out of LLMX"

Onboarding screens:
- "running Codex" → "running LLMX"
- "allow Codex" → "allow LLMX"
- "use Codex" → "use LLMX"
- "autonomy to grant Codex" → "autonomy to grant LLMX"
- "Codex can make mistakes" → "LLMX can make mistakes"
- "Codex will use" → "LLMX will use"

Chat composer:
- "Ask Codex to do anything" → "Ask LLMX to do anything"

Schema name:
- "codex_output_schema" → "llmx_output_schema"
