CAMEL-23634: camel-jbang - TUI Send Message dialog

[davsclaus]

Summary

Adds a "Send Message" action to the TUI F2 actions menu. This lets users send messages to running Camel integrations directly from the TUI — similar to camel cmd send but with an interactive dialog.

Send Message Dialog

• Route selector: cycles through available routes with left/right arrows
• Smart default: prefers direct:, seda:, platform-http: routes (endpoints designed to receive messages)
• Pre-selection: when opened from the Routes tab, the currently highlighted route is pre-selected
• Body text input: type the message body inline
• Header editing: press + to add key-value header rows, Tab navigates between fields, Backspace on empty key deletes the row
• Clipboard paste: Cmd+V / Ctrl+V support via TamboUI bracketed paste mode
• Mode toggle: switch between InOnly (fire-and-forget) and InOut (request-reply) exchange patterns
• Async send: sends on the scheduler thread to avoid blocking the TUI render loop
• Result display: shows elapsed time, reply body (InOut), or error message

Works from any tab since F2 is global. Uses the existing action file mechanism. Headers are sent as JSON array of key/value objects matching CamelSendAction.writeSendData() format.

History Tab Fix

• F5 refresh: F5 now correctly triggers a one-shot refresh of history data (was previously a no-op in the non-trace view)

Test plan

• Build: mvn install -pl dsl/camel-jbang/camel-jbang-plugin-tui -DskipTests
• Run a direct route: camel run tui-hello-world (from examples)
• Open TUI, press F2, Send Message
• Verify route selector shows available routes with smart default on direct:greet
• Type body, press Enter, verify Sent result
• Toggle to InOut mode, verify reply body shown
• Press + to add headers, type key/value, verify Tab navigates between fields
• Backspace on empty header key removes header row
• Paste text via Cmd+V into body field
• Test from Routes tab: select a route, press F2, verify pre-selection
• Switch to History tab, press F5, verify history data refreshes
