[Bug]: Transaction suggested fee rate can display Custom when current fee rate allows for Normal

[catch-21]

Describe the bug

Minor UI bug.

When sending a transaction, it is possible for the fee rate to display as 'Custom' when it is actually using the Normal value. First mentioned here: https://github.com/synonymdev/bitkit/issues/1619#issuecomment-2022813353.

Reproduce

1. Begin constructing a transaction where the sent amount is high enough that the Normal fee rate can be used (it could matter if it is close to not being allowed, or maybe it was recently not allowed)
2. View the suggested fee rate is Custom
3. Tap on Custom
4. Observe that only Custom is seen even though the Normal fee rate is being applied
