Update ethena pt feb emodes

[NandyBa]

Pre-review checklist:

• I have run a spell check on the write-up and made sure no typos exist.
• References to Snapshot/governance forum are correct on the AIP. If no snapshot exists, make sure no TODO's exist.
• The specification on the writeup is aligned with the forum, snapshot, and the payload contract. If there are any changes, they are explicitly mentioned/communicated.
• Minimal tests exist, and the snapshot diff report generated is the latest one and aligned with the payload.
• If deploy scripts are manually updated from the generated ones, I have carefully validated that they are correct, including the deploy commands and the proposal-creation script.
• If the aave-helpers submodule is updated, I have validated it is pointing to the latest version.
• I have validated that no unused files and imports are being added.
• For an asset listing, the write-up includes a detailed specification of the price feed used, CAPO adapters (with each CAPO layer described separately), and eModes (with tables) if changed.
• Wherever possible, I have validated that addresses from the address book are used instead of raw addresses.
