### Description
Tracking issue: https://github.com/wormhole-foundation/wormhole-explorer/issues/569
This pull request adds support for the "Base" blockchain in different parts of the codebase:
* The functions `domain.TranslateEmitterAddress`, `domain.EncodeTrxHashByChainID` and `domain.DecodeNativeAddressToHex`.
* The `tx-tracker` service: it now connects to a Base RPC node to fetch origin transaction metadata.
### Description
This pull request implements an improvement in the processing logic of the `tx-tracker` service to avoid processing a message more than once.
### Description
Tracking issue: https://github.com/wormhole-foundation/wormhole-explorer/issues/499
This pull request adds support in the `tx-tracker` service for the blockchains Terra, Injective, Acala and Karura.
Also, deployment settings were updated with reasonable defaults.
### Description
This pull request adds support for Oasis and Algorand in the `tx-tracker` service.
With this change, the sender addresses for those chains will become available in the UI.
### Description
Tracking issue: https://github.com/wormhole-foundation/wormhole-explorer/issues/418
This pull request modifies the `tx-tracker` service to support `ChainIDTerra2` and `ChainIDXpla`. In particular, this will make sender addresses from these blockchains available for the Wormhole Scan UI.
Support for `ChainIDTerra` was left out due to lack of working public RPC nodes (`https://lcd.terra.dev` doesn't seem to be functioning correctly at the moment).
### Description
This pull request modifies the `tx-tracker` service to support the Moonbeam and Klaytn blockchains.
In particular, this will make sender addresses for these particular blockchains available for the Wormhole Scan UI.
### Description
This pull request adds support for Aptos in the `tx-tracker` service.
This will lead to improvements for the wormhole Scan UI:
1. The transaction hash that was being previously displayed for Aptos VAAs was incorrect. This pull request fixes the issue.
2. The sender addresses for Aptos VAAs will now become available for for the UI.
### Description
This pull request modifies the `tx-tracker` service to support the Sui blockchain.
In particular, this will make the Sui sender addresses available for the Wormhole Scan UI.
### Summary
Tracking issue: https://github.com/wormhole-foundation/wormhole-explorer/issues/404
The WormholeScan UI needs to display the sender address for each token bridge VAA. This pull request modifies the `tx-tracker` service to obtain that information for Solana and eight EVM chains.
The transaction sender will become accessible through the following endpoints:
* `GET /api/v1/global-tx/{chain}/{emitter}/{seq}`: field `originTx.from`.
* `GET /api/v1/transactions`: field `originAddress`.
In both cases, the field is nullable (i.e.: sometimes it may not be available due to eventual consistency or internal errors)
### Summary
Tracking issue: https://github.com/wormhole-foundation/wormhole-explorer/issues/254
For all chains except Solana, the data in `globalTransactions.sourceTx` was somewhat duplicated, since we already had that data in the `vaas` collection.
This pull request changes the `tx-tracker` service so that no redundant data will be written, and also changes the API to look up the data from the `vaas` collection instead.
The responses from the endpoint `/api/v1/global-tx` will no longer contain the field `originTx.from`.
### Summary
This pull request adds the functionality to search for VAAs using Solana tx hashes, e.g.:
`GET /api/v1/vaas?txHash=2qnNNBQQQ152sGkQ1Rnq2Kdr48LvdN4oXwnTWyEmJqYYWFusLWxbwhpGS5KTXH1bKKx9gg9BLZMKd3g1cXiy7QMz`.
Also, the VAA objects returned by the API now have a new field `nativeTxHash`, which contains the tx hash that generated the VAA in the native format of the emitter chain.

### Testing guidelines
Endpoints affected:
* `GET /api/v1/vaas` now supports Solana tx hashes by using the `?txHash=` query parameter. This search is limited to VAAs created by the portal token bridge.
* Some VAAs returned by the API should have a new field `nativeTxHash`. All VAAs related to the portal token bridge should have this field set.
* An internal refactoring affected pretty much all routes under `GET /api/v1/vaas*`, which should be re-tested.
* In the response of `/api/v1/global-tx/`, the field `originTx.signer` has been renamed to `originTx.from`
### Summary
The tx-tracker service was exceeding node RPC rate limits, which caused it to fail.
This pull request changes the APIs upon which the service depends to avoid the same issue in the future.
Also, the backfiller job has been updated accordingly.
