• [x] Align borrow form
• [x] Vault selection’s available route mismatch, crash
• [x] Transitioning Borrow -> Position clears the overview panel, poor transition
• [x] Polygon selected as default instead of user's chain (Federico)
• [x] Set collateral and debt going from markets and positions (Federico)
• [x] Update vault data after changing address (Federico)
• [x] Borrow, choose debt -> Markets -> Borrow again, we see the borrowing form on the right before being centered
