feat(castbars): Add cast bar customizations. Also added canceled / interupted feedback for cast bars.

[Ricoder92]

Summary

This PR expands cast bar customization across Player, Target, Focus, and Boss unit frames while improving border alignment and cast outcome feedback.

Changes

• Added border customizations for Player, Target, Focus, and Boss cast bars.
• Added selectable cast bar textures for Player, Target, Focus, and Boss cast bars.
• Unified border behavior between the cast bar and detached cast icon.
• Added an optional pixel-perfect divider between the icon and bar when the icon is part of the cast bar (for all types of cast bars).
• Fixed some border alignment on the cast bar frame.
• Added configurable cancelled and interrupted cast feedback:
  • Player, Target, Focus, and Boss support
  • Separate enable toggles
  • Separate colors
  • Configurable display durations
  • Interrupted casts use red by default
  • Cancelled casts use orange by default
• Temporarily overrides Hide When Idle while a cancelled or interrupted cast message is displayed.
• Prevents cancelled or interrupted feedback from appearing when Target, Focus, or Boss dies during a cast.
• Ensures new casts immediately replace pending cast outcome messages.
• Added and updated localization entries for the new settings and status messages.

Result

Cast bars now provide more consistent visual customization across unit frames, improved pixel-perfect border rendering, and clearer feedback when casts are cancelled or interrupted.

Screenshots

Settings

Yo another banger PR from you man thank yoU! The core of what i need fixed is that any PR I intake needs to guarantee nothing changes for existing users unless it's specifically a bugfix. Currently there are a few issues on that front:

1. castbarTexture = "none" in defaults kills the health-bar fallback. Defaults get written into the profile, so s.castbarTexture is always truthy and cast bars lose the health bar texture they used to match. Leave the key out of defaults so it stays nil.
2. if inWidth then offX, offY = 0, 0 end silently zeroes existing cast icon offsets and makes the sliders no-ops (in-width is the default).
3. 'The outcome listener isn't gated on the toggles' - it registers UNIT_HEALTH for everyone, and its death/target-change branch hides the cast bar before the enabled check.
4. interrupted and s.interruptedCastEnabled or s.cancelledCastEnabled falls through, so "Show Cancelled" alone also shows interrupted casts. Needs an if/else. Same line in both files.

Thank you for your feedback and your code review! :)

I created a new commit:

1. removed castbarTexture = "none" from the defaults
2. Changed if inWidth then offX, offY = 0, 0 end to:

local layoutOffX = inWidth and 0 or offX
local layoutOffY = inWidth and 0 or offY

and changed following offX/Y to the new variables

3. The listener now registers health, death, and spellcast events only when either Cancelled or Interrupted display is enabled. A second guard inside the handler prevents the feature from hiding cast bars when both toggles are disabled.

4. Replaced the and/or expression with an explicit if/else. This prevents a disabled Interrupted setting from falling back to the Cancelled setting and incorrectly showing interrupted casts. The fix was applied in both files.

Im hoping its fine now :)

Is this still coming into EUI ?
Im missing those things too. Tho at this moment I've just inherit border from health frame.
