Payments for the non abacus works IGP should be highlighted on the explorer

[nambrot]

Once #1736 gets in, indexed payments on the abacus works IGP will be surfaced. However, if a different IGP was used to pay (which may result in non-delivery), the dev can be confused due to the explorer error message of "origin IGP not paid". The explorer should try to find those payments and surface those, with an indication that that maybe a reason for non-delivery

@jmrossy probably overlap with the PI IGP work in #1984 as well

[nambrot]

This detection should also surface if the inner IGP was used and not the overhead igp (when using the abacus works relayer)

[jmrossy]

Halfway there with hyperlane-xyz/hyperlane-explorer#40 but still more to do

[nambrot]

A lot of overlap with #2229 , but this is independently useful for PI chains

[avious00]

@jmrossy would it be possible to see which IGP/relayer was used as a byproduct of this? e.g. a community dev asked to know

if that's a different ask, can create a separate issue

[jmrossy]

@avious00 it would be a pre-requisite for this yes.
