Update ADAView Search to use new POST method

[johnnuy]

Currently with the Version 1.0 API the search address is passed as part of the URL:
https://api.canadastakes.ca/mainnet/api/wallets/

If the address resolves to a wallet identifier then the url will return a 200 OK with the contents:
https://api.canadastakes.ca/mainnet/api/wallets/stake1uylw5ges065hhcexl7vyc8fgpeqpdja9mqlmpxp4fr6lmvsqn9m47

If the address resolves to an address that is part of a larger wallet, then the url will return a 307 with a Location Header pointing to the wallet identifier:
https://api.canadastakes.ca/mainnet/api/wallets/addr1q80vyudy9nltkq30l96h420y66z0srhlrzg3cm569f09yxe7ag3nql4f003jdlucfswjsrjqzm96tkplkzvr2j84lkeqjsknaf

This has the limitation that the address must fit within the max length of a URL. There exists legacy random cardano addresses where this is not the case. As a result the address can now be POSTed to the URL:

https://api-dev.canadastakes.ca/mainnet/api/wallets

with a json request body in the format:
{
"address": ""
}

Sample Large Wallet POST.txt

Which will now return a json response body with the format.
{
"walletIdentifier":"legacy1844q67czzkmz2dc7vjh5k774cks0zhlmvza2q843y38t2fmg2cx",
"message":"Wallet identifier located",
"network":"mainnet"
}

The wallet identifier represents a hashed value of the address that is url safe, and can now be used to retrieve the wallet data as in the 1.0 API:
https://api-dev.canadastakes.ca/mainnet/api/wallets/legacy1844q67czzkmz2dc7vjh5k774cks0zhlmvza2q843y38t2fmg2cx

The wallet identifier returned from the POST should be what is stored in the saved searches, not the original address that was POSTed.

This work can be done on a branch based on the current dev branch.
