Enhancement: Make send confirmation dialog text bigger and format it into groups of 4-5 chars

[tohrxyz]

Is your feature request related to a problem? Please describe.
When pressing send on the transaction, a confirmation dialog pops-up. It asks to confirm the details, but the text in there is too small. Especially when sending Monero, it's long string and too small.

Describe the solution you'd like
I would like to propose making the address text bigger and formatted in groups of 4-5 characters, like Trezor or other wallets display.

So instead of

8BbpkNRq4rW8wu5tHRJDnoPtBSyt3BmwKjXkzKBNs2NaBtRm85YnGqLKomijkvsQ9UWFgXMzhj4mNSgWgZMUz31j7RFoS4n

make it like 8Bbpk NRq4 rW8wu 5tHRJ DnoPt BSyt3... this is far easier to verify, if it's correct.

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

Additional context
I think it would also make sense to go along these lines and format the address string in the receive screen also in the groups of 4-5 chars and make it a bit bigger.

All of this makes it easier to verify addresses.
