feat: support rebalancing via OFT

[grasphoper]

This PR introduces OFTBridge object, which supports sending any token from Ethereum to OFT-supported chain.

I've tested:

• sending tokens L1 -> L2 in via running yarn relay with custom inventory config. tx
• initiation deposit was found successfully and was part of vitrual reserves
• finalization event was found and matched with initiation

P.S. This PR depends on another PR in contracts repo for some IOFT interfaces from typechain.

Closes ACX-3763, ACX-3764, ACX-3765

[linear]

ACX-3763 Create `OFTBrigde` similar to `UsdcCCTPBridge`

ACX-3764 Exclude `USDT` from canonical bridge finalization in `finalizer bot`

ACX-3765 Implement `relayer bot` logic to rebalance tokens between chains

Just to circle back to this:

it'd also be good to check on tests for this code. There are some pre-established tests for these bridge adapters under test/generic-adapters.

Discussed separately - the experience with the existing tests is that they require a lot of boilerplate, such that the ratio of test:implementation starts to become overweight test. It also debatable how useful some of the tests are, since they're typically being implemented against mocked implementations that may not match reality.

The adapter implementation itself is not super complicated; we should instead aim for a future improvement to narrow the scope of our tests for high leverage and low-maintenance testing.

@pxrl @bmzig I've updated this PR and corrected the logic for tracking L1 -> L2 events. Previous if conditions made Hub -> Spoke event tracking incorrect. Please take a look. This is the change b3d65ac
