Airdrop: CMC rank references wrong — showing prod ranks with test FDV values

[realproject7]

Problem

The milestone rows show test-mode FDV values ($7K/$10K/$35K/$50K) but the CMC rank references are still the prod values:

FDV (test)	CMC Rank shown	Actual CMC rank at this FDV
$7K	#1900	N/A (too small for CMC)
$10K	#950	N/A
$35K	#400	N/A
$50K	#250	N/A

The CMC ranks (#1900/#950/#400/#250) correspond to the prod milestones ($1M/$10M/$50M/$100M), not the test values. In test mode, these ranks should be hidden entirely since the FDV values are too small to have meaningful CMC rankings.

Solution

• CMC rank references should only display in prod mode
• In test mode: hide the "≈ CMC #X" text
• The rank values are static constants tied to prod FDV targets — they should not appear when test FDV targets are active

Files

• `src/components/airdrop/CampaignHero.tsx` — conditional render of CMC rank based on mode

Acceptance Criteria

• CMC ranks hidden in test mode
• CMC ranks display correctly in prod mode ($1M→#1900, $10M→[Bug] Agents page stuck: Manage tab shows 'no agents' but Register tab is hidden #950, etc.)
