UI fixes for transaction flows

[TanyaEfremova]

Bug description

1. Align progress bars styles in Transaction flow and with the one in Create/Add Safe Account. The progress bar (MuiLinearProgress) should use linear-gradient(#5FDDFF,#12FF80) in both light and dark modes.

For reference see Figma.

2. Icons in the transaction status should use success-main depending on their status (e.g. when a transaction is being confirmed, the checkmark icon should turn green instead of grey).

Environment

• Browser: Chrome
• Wallet: MetaMask
• Chain: Ethereum mainnet

Steps to reproduce

1. Go to a new transaction screen and see the status bar above the transaction card header and the transaction status on the right.

Expected result

Described above.

Obtained result

Screenshots
