QuadHeal party and raid frame overlay (NEW)

# QuadHeal 0.23.2

QuadHeal is getting slightly out of hand. What started as a healer helper now wants more of your mouse buttons, remembers your specs, and lets you heal yourself straight from the Spell Map. Healers may still be the main crowd, but other specs are welcome to the party too.

## Changes since the 0.19.4 package

- Separate Solo, Party / Dungeon and Raid controls for icon positions, icon visibility and indicators, with the indicator legend alongside the controls.
- Settings previews follow the selected context and use observed Blizzard frame dimensions when available. When no frame is available, the preview is labelled as an example.
- Added a recommendation to enable raid-style party frames for the best results in a party.
- Added Copy Settings and Import Settings with specialization checks. JSON uses named settings, supports missing or new fields, and older export codes remain supported.
- Settings now follow your specialization, including layout mode, active mouse buttons, icon settings and Spell Map settings. New specs start in Normal mode with left and right mouse buttons enabled.
- Fixed settings refresh and Save / Cancel behavior when switching specs.
- Made the Spell Map clickable using the same mouse bindings as the matching unit-frame area. Map spells always target yourself, including during combat: your own little solo healing station.
- Added a cogwheel to open settings from the Spell Map.
- Removed spell-area tooltips from the Spell Map and added a Solo settings tip about using it to heal yourself.
- Made the settings background more opaque and brought the copy/import window to the foreground.
- Updated the help text and website link to www.darqside.org.

Layout and binding changes that need secure frame updates apply after combat. Cooldowns continue updating during combat.
