Soldity Stablecoin/RWA - Replace ERC20Blocklist/ERC20Allowlist with ERC20Restricted

[ericglau]

From Stablecoin or Real-World Asset tabs, Limitations has Allowlist and Blocklist which use ERC20Allowlist and ERC20Blocklist. However, these contracts are deprecated as stated in their NatSpec.

Replace these with ERC20Restricted.

This may require some design in terms of how the options appear the UI and what the resulting contract should look like.
