CAMEL-23615: camel-tui - Fix unsafe type casts and unguarded parsing

[davsclaus]

Summary

• Fix unsafe (Boolean) cast from JSON for polling field — use Boolean.TRUE.equals() instead
• Fix unsafe (Boolean) casts for done/failed fields in history entry parsing
• Guard Long.parseLong(ctx.selectedPid) with try-catch on tab switch to history

Test plan

• Builds clean
• Manual: TUI operates normally with consumer tab, history tab, and endpoint views

Good defensive coding fixes for the TUI:

1. Wrapping Long.parseLong(ctx.selectedPid) in try-catch for NumberFormatException — prevents crash on unexpected PID values.
2. Replacing unsafe (Boolean) json.get("done") / (Boolean) json.get("failed") casts with Boolean.TRUE.equals(...) — avoids ClassCastException if the JSON value isn't a Boolean object.
3. Same fix for cj.get("polling") in parseIntegration.

All three changes follow the same pattern: replacing unsafe assumptions about runtime types with null-safe, cast-safe alternatives.

LGTM.
