[bug] invalid price defaults to 0tz

[Zir0h]

Describe the bug

Hey sorry to bother you but my friend told me you’re a teia dev! I just wanted to let you know that I happened to list a piece twice today from the http://teia.art site and both times it was listed at 0 xtz instead of 3.5 as I intended. It’s the second time it happens to me, not a big trouble but I just wanted to let you know in case there might be some sort of bug on the platform. Hope it helps!

Reproduction

swap an objkt for 3,5 tez (hence the comma)
check the rpc call
see that it put 0 as price, and not 3500000

Expected behavior

should abort transaction and show an error

Platform and versions

- Linux
- FF 125.0.1

Console output

NaN with 3,5 as input
3.5 with 3.5 as input

would catch the "invalid input"

because in the current implementation, if you put "1,1" it gets translated to empty string "" and passes those checks

the onBlur validation doesn't seem to work 😅
