chore: Miscellaneous refactoring/cosmetic changes

[svienot]

Description:

A few unrelated small refactoring or cosmetic changes, with no impact on the functionality, except for those 2 items:

• use Cloudflare public IPFS gateway instead of ipfs.io (usually responds more reliably)
• add Show raw data link in NftDetails view

Notes for reviewer:

Should not have any impact on tests.
