MidnightNameplates 0.11.0.1 - Phase 11.0.1 Delve Context Support

NEW
- DELVE is now a first-class PvE Intelligence context.
- Dedicated "Enable in Delves" Intelligence toggle.
- Profiles page now supports assigning a separate Delve profile.
- Intelligence page reports DELVE and, when available, the active Delve tier.

DETECTION
- Uses C_DelvesUI.GetActiveDelveTier() as the positive Delve signal.
- Does NOT classify every generic instanceType="scenario" as a Delve.
- Generic scenarios remain OTHER unless Blizzard's DelvesUI API confirms an active Delve.

TEST
1. Open /mnp -> Intelligence outside a Delve: should not say DELVE.
2. Enter a Delve: context should change to DELVE.
3. If Blizzard exposes the tier, the Intelligence page should display it.
4. Create a HIGH/CRITICAL NPC rule and verify Intelligence emphasis in a Delve.
5. Disable "Enable in Delves": rule styling remains, but PvE Intelligence emphasis stops.
6. Profiles -> assign a separate Delve profile.
7. Enable automatic context profiles and enter/leave a Delve.
8. Normal scenarios must not be mistaken for Delves.
9. Dungeon/Mythic+/Raid detection remains unchanged.
10. Friendly-player auras, import/export, profile confirmations and mailbox filter remain working.
11. No Lua/taint/secret-value errors.
