ZEUS-2491: force user to set rate on mempool fee suggestion error

[kaloudis]

Description

Relates to issue: ZEUS-2491

• Users must now manually set a fee rate when mempool fee suggestion fails, when opening a channel, closing a channel, or making an on-onchain transaction
• Opening a channel, closing a channel, and making an on-onchain transaction is blocked when the fee rate is set to 0 sats/vbyte
• On the Open Channel view the fee input form is now moved out and above the Advanced settings section
• Fixes display of the icon on the Open Channel button on the Open Channel view
• OnchainFeeInput: when suggestions are disabled, force users to manually set the fee rate before proceeding

Very nice, just one thing needs to be fixed:
You can still close a channel without setting a custom fee rate (button 'CONFIRM CHANNEL CLOSE' ist not disabled).

This is intentional as the fee rate on the CloseChannel call is optional https://lightning.engineering/api-docs/api/lnd/lightning/close-channel/index.html

Ah of course, the nodes negotiate the fee, I forgot :)

Then it's good to go imo.
