### Description
This pull request removes duplicated code related to MongoDB connection/disconnection attempts. This code was copied across all 8 microservices.
The functionality is now unified under the `common/dbutil` package.
### 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})`
* Add unknown guardian set index alert
* Add prometheus metrics to check if exists observations without txhash
* Add max sequence cache error prometheus metrics
Add environment variables for buffer channels (observations y vaas)
Increment size of buffer channels for observations and vaas
Align k8s resources in fly

### 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/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
Tracking issue: https://github.com/wormhole-foundation/wormhole-explorer/issues/535.
This pull request fixes an inconsistency between the endpoints `GET /api/v1/x-chain-activity` and `GET /api/v1/top-chain-pairs-by-num-transfers`.
The inconsistency arose because the endpoints computed the data in slightly different ways.
It was resolved by modifying the `GET /api/v1/top-chain-pairs-by-num-transfers` endpoint to use the same data source as `GET /api/v1/x-chain-activity`.
### Summary
This pull request changes the retry logic in the `tx-tracker`.
When failing to process a transaction, the associated SQS message will be left to expire and will reappear after `visibilityTimeout` seconds. As a side effect, there will be several retries before giving up.
### Description
This pull request removes two unused fields from the `GlobalTransaction.OriginTx` JSON model:
* `timestamp`: this field is always set to the VAA's timestamp, making it redundant. Moreover, for EVM chains we need one extra RPC node request to get it. So better get rid of it.
* `chainId`: this field is always set to the VAA's emitter chain, making it redundant.
### Summary
This pull request modifies the API service to expose two endpoints for the Wormhole Scan UI:
* `GET /api/v1/transactions`: data needed to render the transactions list page.
* `GET /api/v1/transactions/{chain}/{id}/{sequence}`: data needed to render the transaction detail page.

### 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
This pull request implements improvements in the `tx-tracker` service:
* Adjust SQS visibilityTimeout.
* Process PythNet messages concurrently (this will make it easier for the service to catch up if there are a lot of messages in the input queue).
* Add more context information to error messages.
