rABCb137fcf02fa4: [Cashtab] [Alias] pt 4 - Implement isAddressRegistered function

Summary

T2551

Depends on D12907

This diff fleshes out the isAddressRegistered function which is called upon loading the Alias component to check whether the current active wallet has any onchain aliases attached to it.

The payment address tx history retrieval logic was moved into it's own getAliasPaymentHistory function so that it can be reused by both isAddressRegistered and isAliasAvailable.

isAddressRegistered basically filters for valid incoming registration transactions at the alias payment address and extracts the hash160 of inputs[0] (the sender address of a valid registration tx) and compares it to the active wallet's hash160 (wallet.Path1899.hash160).

In later diffs the chronik API calls in isAddressRegistered will retrieve cached tx histories if the tx count of the alias payment address has not changed.

[Cashtab] [Alias] pt 6 - Implement isLocalAliasStateLatest function
[Cashtab] [Alias] pt 7 - Enable alias lookup for Send XEC component
[Cashtab] [Alias] pt 8 - Enable alias lookup for Send Token component
[Cashtab] [Alias] pt 9 - Implement pricing mechanism
[Cashtab] [Alias] pt 10 - Server cron job
[Cashtab] [Alias] pt 11 - Upgrade tx history to recognize alias registration txs

Test Plan

npm test
npm start
use a wallet that you have previously registered an alias with from part 3 of this stack
navigate to the Alias page and verify the 'Does this active wallet have an onchain alias? : true' console log message is displayed
switch to a wallet that did not previously register an alias then navigate to the Alias page and verify the 'Does this active wallet have an onchain alias? : false' console log message is displayed

For both isAliasAvailable and isAddressRegistered, the input data should be the same. The missing piece here is a fetchAndCacheValidAliasesThroughLatestBlock function. This should return an object that looks something like

{
  validAliases = {registeredAliases: [{alias: alias1, address: address1}, {alias: alias2, address: address2}, ... , {alias: aliasN, address: addressN}] 
  validThruBlockheight: <blockheight where registeredAliases is valid through>
}

web/cashtab/src/utils/chronik.js
162 ↗	(On Diff #37547)	I'm not sure this function is necessary. Once this system is live, the behavior we want is On Cashtab load, update alias list to current blockheight If we have an `isAddressRegistered` function, it should only be checking localStorage As time goes on, we could add checkpoints -- i.e. add list of aliases, addresses, and blockheight to which the list is valid to `currency.Ticker` instead of `localStorage`, so that new Cashtab users aren't forced to parse the whole tx history of the alias address when they first use the app. So, instead of implementing caching in this function -- this function should just depend on the output of the `extractAliasesFromPaymentAddress` function from Part 2
164 ↗	(On Diff #37547)	local storage should preserve a list of valid alias registrations, their address, and the blockheight to which it is valid

This revision now requires changes to proceed.Jan 17 2023, 23:45

refactored isAddressRegistered to parse a mocked (for now) localStorage object rather than an onchain call to chronik
removed runtime hash160 address conversions as per D12907
