Airdrop: innovation banner follow-up — 2-column comparison only

[realproject7]

Problem

The innovation banner still needs a follow-up pass with the updated scope. Reusing the earlier closed issue causes queue tracking to attach an old PR, so this work needs a fresh issue.

Scope

Update the innovation banner on the airdrop page to use a direct two-column comparison only:

• Typical Airdrop
• This Airdrop

Specific changes:

• Remove the staking column entirely
• Use the wording "Dumps on day 1"
• Keep the contrast focused on why this mechanism is different
• Use "MCap" terminology in the supporting copy

Placement

Below CampaignHero, above the UserPoints/Leaderboard grid.

Files to modify

• src/components/airdrop/InnovationBanner.tsx

Acceptance Criteria

• Two-column comparison only (Typical Airdrop vs This Airdrop)
• No staking column
• "Dumps on day 1" wording is used
• Supporting copy uses MCap terminology
• Responsive layout: side-by-side on desktop, stacked on mobile
