Locales: koKR update -- new keys, section reorganization

[labrie75]

What does this PR do?

koKR-only update to Locales/koKR.lua. No code changes.

Area	Change
New keys	+61 (no keys removed, English untouched)
Reorganization	keys previously appended at the file bottom moved into their -- == add <Module> sections
Consistency	a few existing values reworded to match in-game terms (commented inline)

Added

• Unit Frames: "Show Tooltip For" checkbox-dropdown items and tooltips
• Cooldown Manager: Reverse Fill / Fill Up / out-of-combat hide tooltips
• Resource Bars: Smooth Bar Animation, GCD bar "Show Fill Color When Idle"
• Unlock Mode: "(Width/Height) matched to (bar). Unmatch in Unlock Mode to edit." -- the source builds this by concatenation, so the common axis x bar-name combinations are registered as full-string keys
• Minimap: Addon Compartment toggle/scale/tooltip
• Chat: tab cog popups (Tab Layout / Tab Background / Active Tab Background)
• Bags: Sort Options cog, QoL: Hold Capped Artisan Payouts, Party Mode: Spin cog
• Chat prints: a dedicated section at the bottom collecting every user-facing
  chat message (print / EllesmereUI.Print / instance-reset SendChatMessage
  defaults). Keys are exact source literals incl. color codes. Messages whose
  call sites are not yet L-wrapped are data-only for now and light up with a
  future wrapping PR; the already-wrapped ones (Raid Tools, auto-repair,
  auto-sell) translate immediately.

Changed (existing values, inline-commented)

• "Raid" prefix on Raid Tools strings now matches the tab name (레이드 -> 공격대)
• Pull timer strings unified to 초읽기 (countdown) across Raid Tools and CDM
• "Offset" values unified to 위치 (position), matching X/Y Offset keys
• "Match Damage Meters" shortened so it fits the dropdown width

Reorganized

• Keys that had accumulated after the M+ abbreviation block are distributed
  into their module sections; the M+ keystone block stays last.

How was it tested?

Loaded on the 12.1 PTR with a koKR client: options panel pages for Unit
Frames, CDM, Resource Bars, Minimap, Chat, Bags, QoL and Party Mode render the
new strings; terminology changes verified on the Raid Tools tab. File parses
clean; 0 keys removed, so every previously translated string is unchanged
unless listed above.

• New settings default OFF (no behavior change without opt-in)
• Zero cost while disabled: no events registered, no polling, no hooks doing work, no frames built
• Cheap while enabled: event-driven (no polling, no timer-based logic, no per-frame allocations)
• No writes onto Blizzard-owned frames (weak-table pattern used); HookScript/hooksecurefunc only, never SetScript on Blizzard frames
• Tested in-game, works on live retail; no load errors on the 12.1 PTR client
