CAMEL-23855: Add F8 AI prompt panel to TUI

[davsclaus]

Summary

• Add F8 AI prompt panel to TUI for interactive AI assistant (works with or without --mcp)
• AI panel supports split view (25%/50%/75%) with Shift+F8 to cycle
• AI Log popup (via Actions menu) shows tool calls, results, and responses
• Add 10 missing MCP tools to AskTools: get_memory, get_errors, get_history, get_variables, get_services, get_route_topology, send_message, eval_expression, browse_endpoint, get_thread_dump
• Fix shell scrollback: use private field reflection for JLine's ScreenTerminal.history (no public API exists), change to plain PgUp/PgDn instead of Shift+PgUp/PgDn
• Comprehensive test coverage for TUI (borders, key parsing, tab rendering, fuzzy filter, shell panel, etc.)

Test plan

• Start TUI without --mcp, verify F8 AI panel is shown in footer and opens
• Start TUI with --mcp, verify AI panel works with tool calls
• Open AI panel, ask a question, verify auto-scroll and dimmed elapsed time
• Cycle AI panel size with Shift+F8 (25% → 50% → 75%)
• Open shell (F6), verify PgUp/PgDn scrollback works
• Open Actions menu, verify AI Log entry shows tool call history
• mvn test passes in camel-jbang-plugin-tui
