TextLocator/implement literature search

[warm-coolguy]

Summary

• Implemented document search, that is, the AddressSearch bar now also offers results for documents, and clicking on one will retrieve a list of toponyms from the backend and resolve them against the gazetteer. Previously, we had a "get all documents regarding place" functionality. Now, a "get all places regarding document" feature is implemented.
• Additionally to the AddressSearch, this can be triggered on documents found in the previously implemented way; the "get all places regarding document" functionality is available from within the GeoSearch result display with one of the right-hand buttons.
• The backend API changed. The changes have been adapted to.
• The "heatmap" feature is currently not working. This will be adressed in a follow-up PR. For now, the feature correctly zooms, but the map stays cold. (Fix/text locator heatmap #195)
• The result display may become confusing due to a growing number of ways to fill in the contents. To address this issue, further context information ("How did I get this result?") will be added in a separate PR. (Feature/text locator result source indicator #194)

Instructions for local reproduction and review

npm run textLocator:dev

• Test new search features.
  • (AddressSearch) Try searching for "Marine" and clicking the first literature result. (Other results may not yield toponyms relevant to the used gazetteer.) (Edit: Meanwhile, wildcard has been implemented. Also search for "Marin" to see if it works; should yield results now.)
  • (GeoSearch) Click into the map, e.g. on Neuwerk. In the result section, when having "Text" as sorting order, click the magnifying glass icon to load all geometries regarding any text.
• Since the backend API was changed and everything required touching, testing everything across the board seems to be in order. Exceptions have been noted in the Summary.

After clicking myself through the related places to A review on substances and processes relevant for optical remote sensing of extremely turbid marine areas, with a focus on the Wadden Sea it is a bit confusing to me why some places have highlighted geometries and others don't. How does this happen? Is this something that is addressed in #194?

Actually, all places have geometries, but not all are clearly visible.

• Norderney is a split geometry of two smaller things and may be hard to see (maybe it's something rare, like Neuwerk, which is part of Hamburg – for our concern, we trust the geographic data is correct as presented)
• Some entries are just off-limits the map in the new data set; since we're focusing on the North Sea Coast, I deem this an issue of the underlying testing data atm; I'll note that in the internal issue tracker

Actual highlighting (making places brighter/darker) is a concern of that PR, yes.
