Clean up factory vault metadata and remove stale Curve factory copy

[rossgalloway]

Summary

Clean up factory vault metadata / yCMS copy and verify whether the earlier Curve factory vault description cleanup already landed.

Problem

Factory vault metadata still appears to include outdated template language such as:

"This token represents a Curve liquidity pool. Holders earn fees from users trading in the pool, and can also deposit the LP to Curve's gauges to earn CRV emissions."

Proposed changes

• update metadata for factory vaults
• audit whether a prior cleanup PR already exists or merged
• replace outdated template copy where it is still present

Acceptance criteria

• stale Curve-LP template text is removed from affected factory vault metadata
• current metadata reflects the actual vault/product behavior
