Return Mapeo data in `alerts/` GET endpoint; add Mapeo alert data to `AlertsDashboard` component

Feature Request

To complete the end-to-end alerts workflow, we need to show Mapeo data related to the alerts on the Alerts Dashboard. To accomplish this, we need to know the following information at minimum:

1. What is the name of the db table where the Mapeo data is stored.
2. What are the categoryIds from the Mapeo configuration that are relevant to alerts.

With this information, we can expand the /{table}/alerts API endpoint to query the db table for only those categoryId specified in the env var, include it in the response.

From there, we can add the Mapeo data to the map much like we do for the Map view, with a Mapbox event listener to open the Mapeo data in the sidebar.

Implementation Plan

• For VIEWS: "alerts" arrays in NUXT_ENV_VIEWS_CONFIG, add additional keys MAPEO_TABLE and MAPEO_CATEGORY_IDS (which takes multiple comma-separated values, that should match the Mapeo config categoryId)
• Supply these env vars to the /${table}/alerts GET endpoint; query the db to retrieve only values with categoryId match, store those in a mapeoAlertsData object to be added to the endpoint response.
• Pass mapeoAlertsData object to AlertsDashboard.vue component and add the data to the Mapbox map with event listeners to show Mapeo data in the sidebar on click, akin to how things are done in Map.vue.
