What & why

Each raw file asset already fetches or parses its source's release date to write the metadata.json sidecar, but never reported it to Dagster, so the UI couldn't show which release a download holds. The raw file assets of DAC1, DAC2A, DAC2B, CRS, WEO, IDS and Imputed Multilateral Sectors now report it as YYYY-MM-DD metadata, under the sidecar's keys (source_release_date, or crs_release_date and multisystem_release_date).

Closes #50

Changes

• Each raw file asset adds the date it already holds to its materialization metadata. CRS and WEO keep the parsed or fetched date in a variable, since it is now used twice.
• Each raw file test asserts the new key.

Notes for reviewers

• The observations and exports report no date. An observation already identifies a release by its version metadata, and a date there would cost a second request a day that must not fail release detection. What the graph serves is on its provenance's importedSourceReleaseDate.
