### Description
This pull request adds the parameter `toChain` to the endpoint `GET /api/v1/vaas/{emitterChain}/{emitterAddress}`.
Other VAA-related endpoints do not support this parameter.
Additionally, for performance reasons, a composite index must be created in MongoDB: `db.parsedVaa.createIndex({"emitterChain": -1, "emitterAddr": -1, "rawStandardizedProperties.toChain": -1, "indexedAt": -1})`
### Description
Before this pull request, when calling `GET /api/v1/vaas?txHash={h}` for a hash that has multiple VAAs associated with it, we were just returning one. After this pull request, the API should return all of the VAAs associated with that transaction hash.

### Description
Tracking issue: https://github.com/wormhole-foundation/wormhole-explorer/issues/451.
The Wormhole Scan UI needs to provide a link to the emitter address for each VAA.
This pull request adds a field containing decoded emitter addresses in the following endpoints:
* `GET /api/v1/transactions`: field `emitterNativeAddress`
* `GET /api/v1/vaas*`: field `emiterNativeAddr`
### Description
Remove the `NativeTxHash` from the JSON model returned by `GET /api/v1/vaas`. That field was never meant to be exposed to the API users.
For Solana and Aptos, the transaction hash returned by `GET /api/v1/vaas` is incorrect (currently it's the value transmitted in the gossip network, which is not the real transaction hash).
This pull request replaces it with the real transaction hash.
### Summary
This pull request adds volume metrics to influxdb. Also, it adds the 24h volume metric to `GET /api/v1/scorecards`.
Tracking issues: https://github.com/wormhole-foundation/wormhole-explorer/issues/221, https://github.com/wormhole-foundation/wormhole-explorer/issues/280
### Changes:
* The `parser` service no longer generates metrics for influxdb. All metrics-related code was removed from that service, that code was moved to the analytics service instead.
* New volume metrics were added to the analytics service.
* The notional cache was modified to use token names (i.e.: ticker symbols) as keys instead of chain IDs.
* The notional cache reader was moved to the `common/client/cache` package.
* A little bit of duplicated code between the cache reader and writer was removed.
* A 24h volume metric was added to `GET /api/v1/scorecards`.
* A dictionary that stores token metadata was added under `common/domain/tokenbridge.go`. More tokens will be added to it in the near future.
### Summary
The output of `GET /api/v1/vaas` was not being correctly sorted. This pull request changes the behavior so that the output will be sorted by the `timestamp` field.
Additionally, duplicated code was removed in the VAA code that handles queries.
Also, there was an unused query parameter `sortBy` which was being exposed but not used. Hence it was removed.

### 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
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}`
### 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
In some cases, the query parameters for a MongoDB aggregation pipeline were not being initialized.
This led to errors in `GET /api/v1/vaas/{chain}/{emitter}/{seq}`.
Other endpoints could also have been affected.
### Summary
* On all endpoints, fix the behavior of the `page` parameter (which was previously being ignored).
* On `GET /api/v1/vaas`, fix the behavior of the `sortBy` parameter (which wasn't working when `parsedPayload=true`).
* For all endpoints, validate the query parameters `page`, `pageNumber` and `sortOrder`.
* Return descriptive errors when pagination-related parameters happen to be invalid (`page`, `pageSize`, `sortOrder`).
* Validate guardian addresses in query params.
### Testing plan
All parameters involved were manually tested.
### Summary
Split `/v1` and `/api/v1` controllers into different packages (respectively `api/routes/guardian` and `api/routes/wormscan`).
Still need to move services/repositories/models according to the new package layout.
* add vaaId and txHash relation in vaaIdTxHash collection
* add txHash in vaas collection
* add txHash in response vaa and as filter in find vaas endpoints
* Add use of sequence cache in API
* Add sequence cache in fly
* Deploy for API
* Improve use cache in API
* Remove sequence cache in fly for pythnet
