[Bug]: No minimum receive amount or LSP fee, and CJIT Error when attempting to receive spending balances when network is down

[catch-21]

Describe the bug

Created off the back of https://github.com/synonymdev/bitkit/issues/1833#issuecomment-2133657792

$0 receive minimum, $0 LSP fee and CJIT Error: init_channel_manager or CJIT Error: Failed to create cjit entry. undefined toast is displayed when attempting to receive spending balance without an existing LN connection. We should handle this better in the UI, perhaps preventing progression when unable to contact LSP.

Reproduce

This is easy to reproduce in aeroplane mode but it can also occur when network is down or restricted

1. With no existing LN connection
2. Enable aeroplane mode to stop network
3. Attempt to receive lightning funds
4. Observe $0 minimum
5. Continue
6. Observe $0 LSP fee
7. Continue
8. Observe cjit error
