### 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.
Tracking issues: https://github.com/wormhole-foundation/wormhole-explorer/issues/212, https://github.com/wormhole-foundation/wormhole-explorer/issues/214
### 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.
Tracking issue: https://github.com/wormhole-foundation/wormhole-explorer/issues/205
### Summary
Several endpoints related to VAAs and observations returned `null` when no results were found.
This commit changes the behavior to return `[]` instead, which is more ergonomic for users.
Endpoints affected:
- `GET /api/v1/observations/:chain`
- `GET /api/v1/observations/:chain/:emitter`
- `GET /api/v1/observations/:chain/:emitter/:sequence`
- `GET /api/v1/observations/:chain/:emitter/:sequence/:signer/:hash`
- `GET /api/v1/vaas/{chain_id}`
- `GET /api/v1/vaas/{chain_id}/{emitter}`
- `GET /api/v1/vaas/{chain_id}/{emitter}/{seq}`
Fix governor endpoints
A few governor endpoints were handling addresses incorrectly,
which resulted in errors.
* `GET /api/v1/governor/config/{governor_address}`
* `GET /api/v1/governor/status/{governor_address}`
This commit fixes the issue and adds doc comments to prevent the
same caveat from happening again in the future.
### Summary
This PR enables passing emitter addresses in Solana format when the `chainId` parameter is set to 1. If `chainId` is set to a different value, the API will expect a regular Wormhole address.
Tracking issue: https://github.com/wormhole-foundation/wormhole-explorer/issues/189
### Endpoints affected
- `GET /api/v1/global-tx/{chain_id}/{emitter}/{seq}`
- `GET /api/v1/observations/:chain/:emitter`
- `GET /api/v1/observations/:chain/:emitter/:sequence`
- `GET /api/v1/observations/:chain/:emitter/:sequence/:signer/:hash`
- `GET /api/v1/vaas/{chain_id}/{emitter}`
- `GET /api/v1/vaas/{chain_id}/{emitter}/{seq}`
### Example
These two calls should be equivalent:
- `GET /api/v1/vaas/1/ec7372995d5cc8732397fb0ad35c0121e0eaa90d26f828a534cab54391b3a4f5` (address in Wormhole format)
- `GET /api/v1/vaas/1/Gv1KWf8DT1jKv5pKBmGaTmVszqa56Xn8YGx2Pg7i7qAk` (the same address, in Solana format)

### Summary
This pull request adds a new component under the directory `txtracker`.
This component retrieves information about portal token bridge transfers (i.e.: sender address, receiver address, timestamp), and persists the data in MongoDB.
### Chains supported
The blockhains currently supported are:
* Terra (27% of outgoing transfers)
* Solana (25%)
* BSC (25%)
* Eth (14%)
* Polygon (4%)
The remaining chains will be added iteratively as needed.
### Summary
Context: https://github.com/wormhole-foundation/wormhole-explorer/issues/154
This PR modifies all endpoints that receive an emitter/guardian address to accept a wider range of formats.
After this pull request, all of these are equivalent:
* `0x000000000000000000000000f890982f9310df57d00f659cf4fd87e65aded8d7`
* `000000000000000000000000f890982f9310df57d00f659cf4fd87e65aded8d7`
* `0xf890982f9310df57d00f659cf4fd87e65aded8d7`
* `f890982f9310df57d00f659cf4fd87e65aded8d7`
### Testing plan
* Added unit tests for the parsing code.
* Tested manually a few of the affected endpoints.
### Summary
* Swagger: remove `sortOrder` query parameter from several endpoints in which it didn't make sense.
* Swagger: remove query params `page` and `pageSize` from endpoints that return a single object.
* Sort the output of `GET /api/v1/governor/config` by ascending id.
* Refactor: remove duplicated code, format code for readability.
The API's swagger documentation exposes a route
`GET /api/v1/governor/max_available/:chain`,
but instead it should be
`GET /api/v1/governor/notional/max_available/:chain`.
### Summary
Changes to `GET /api/v1/governor/limit`:
* Fix the behavior of the parameters `page` and `pageSize` (which previously were being ignored).
* When no results are found, return an HTTP status code of 200 and set the response to an empty array.
* Remove the `sortOrder` query parameter.
The rationale for removing the `sortOrder` parameter is that sorting chains by ascending/descending chain ID doesn't seem to be a useful operation.
