feat(backend): validate GDAL tiles through the GDAL worker pool (#1421)

* feat(backend): validate GDAL tiles through the GDAL worker pool

Adding tiles to a dataset opened every local tile file with GDAL in the server
process, synchronously on the async runtime. The worker gains a header request
that returns the band's data type and the file's CRS without reading pixels, so
requests are now either a pixel read or a header read, and both share the pool's
join of identical requests and the retry around opening a file.

`CannotGetRasterDescriptorFromTileFile` is folded into `CannotOpenTileFile`,
which now carries the pool error. External tiles are still not opened.

Adapted from 285082259 and c4337bf62 of feat/md-gdal-source, without the
multidimensional reads.

* fix(backend): log fatal worker IPC errors through tracing

The subscriber is set up before run(), so the error reaches the worker log
and OpenTelemetry instead of bare stderr.
