Robui

Vehicle handling fixed.
RobUI now correctly switches to Blizzard’s default vehicle UI when entering vehicles.

Player frame stability improved.
Health and power text always regenerate from live values, fixing update issues after login and spec swaps.

Class/resource rebuild logic cleaned up.
Segment-based resources no longer risk partial builds or nil errors.

Empower castbar corrected.
Segments build properly and stop immediately on completion or interruption.

Added XP Time-to-Level frame.
New /rxp slash command toggles a lightweight XP bar that estimates time remaining to level based on current XP gain rate.

Improved initialization timing, removed unsafe secret comparisons, and reduced unnecessary refresh loops.
