ui(fb): display warning if all funds are used for fidelity bond

[theborakompanioni]

Mitigate cases described in #597.

Adds a warning to the Fidelity Bond Form, when all UTXOs are selected:

Keep in mind: As you are using all available funds for the creation of this fidelity bond, you will not have any UTXOs left. A fidelity bond will not participate in collaborative transactions and you have to fund your wallet again to start sending or earning.

Additionally:

• Fidelity Bond component transformed from jsx to tsx -> this still needs additional refactoring, but as a redesign is already planned, no further changes were made (issue ui: redesign fidelity bond creation flow #650)
