Rename perpetualModify to perpetualModifyPosition for clarity

[Copilot]

Addresses review feedback on #1332 to rename the perpetualModify enum case to perpetualModifyPosition for consistency with related perpetual transaction types.

Changes

• Renamed TransactionType.perpetualModify → TransactionType.perpetualModifyPosition in generated type definition
• Updated all references across 12 files:
  • Transaction filtering and view models
  • Transfer confirmation UI sections
  • Transaction header builders and view models
  • Test cases

// Before
case perpetualModify

// After  
case perpetualModifyPosition

This aligns naming with perpetualOpenPosition and perpetualClosePosition, making the enum value more descriptive of its purpose.

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• just.systems
  • Triggering command: curl --proto =https --tlsv1.2 -sSf https://just.systems/install.sh (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
