[Bug] E2E Mainnet Script Must Forward Creation Fee on Storyline Creation

[realproject7]

Summary

The merged mainnet E2E script from #27 fails when executing StoryFactory.createStoryline() on Base mainnet because it does not forward the required MCV2_Bond creation fee.

Failure

Execution from #29 hit:

• MCV2_Bond__InvalidCreationFee()

T3 reported that Base mainnet currently requires 0.0007 ether per createToken call. The E2E script creates 6 storylines, so the script must fund those calls with the required msg.value.

Scope

Update script/E2ETest.s.sol so every StoryFactory.createStoryline() path forwards the required creation fee.

Acceptance Criteria

• Every createStoryline() call in script/E2ETest.s.sol forwards the required creation fee
• The script no longer reverts with MCV2_Bond__InvalidCreationFee() on Base mainnet
• Issue [Test] Run E2E Mainnet Test Suite #29 can be re-run successfully past storyline creation
• PR includes the correct original issue number in the title

Notes

• T3 observed 6 storyline creations in the script (A1, A2, A3, F1, F2, F3), which implies 6 x 0.0007 ether = 0.0042 ether total at the current fee
• Validate the exact fee source in code/config rather than hard-coding assumptions where avoidable
