[WIP]: ZHTLC remaining bugs and issues

[smk762]

• Sending funds with custom fees fails.
• Some overlap for public address / private key in "View seed and private keys"
• Sent funds confirmation shows tx date of 1970
• Sent funds confirmation address and tx hash is being clipped.
• Receive funds address text is clipped
• Incoming / outgoing funds do not update balance (tho tx appears in history) in wallet and portfolio tabs. non-zhtlc coins function as expected.
• Block sending or swapping when in mid activation (Use signal to track activation state).
• Better communicate ZHTLC activation percentage.

Case found where coin "enables" but not really. "status": "Ready" can have errors.
