Shipped PhotometryFilters.json has Paranal/VISTA bands with no matching Paranal row in Telescopes.json/Instruments.json

**Where:** `data/reference/PhotometryFilters.json` already contains `Paranal/VISTA.Y`, `Paranal/VISTA.J`, `Paranal/VISTA.H`, `Paranal/VISTA.Ks` (and other pre-populated bands like `PAN-STARRS/PS1.y`, `UKIRT/WFCAM.*`, `UKIRT/UKIDSS.*`, `UKIRT/UFTI.*`), but `data/reference/Telescopes.json` has no `Paranal` row at all (only `VLT-UT1..4` for that facility) and `Instruments.json` has no matching `Paranal` instrument row either.

**What happened:** A downstream skill's pattern of skipping `ingest_photometry_filter` when a band already exists in `PhotometryFilters` (since `ingest_photometry_filter` raises "already exists") meant the Telescopes/Instruments setup that `ingest_photometry_filter` would normally do as a side effect never ran for these pre-shipped bands. `ingest_photometry(..., telescope="Paranal", ...)` then failed for every VHS/VIKING/VVV/VIRAC2 magnitude with `Telescope Paranal not found in Telescopes table.` — 299 rows skipped on the first dry run of a real ingest.

**Suggested change:** Add a `Paranal` row to `data/reference/Telescopes.json` and a matching `VISTA` instrument row to `data/reference/Instruments.json`, and audit for other pre-populated `PhotometryFilters` bands with the same gap (any telescope/instrument referenced by a shipped filter row should have a matching row in both tables).

**Cross-filed:** Also filed against the [astrodb-bot](https://github.com/astrodbtoolkit/astrodb-bot) skills repo as [astrodbtoolkit/astrodb-bot#102](https://github.com/astrodbtoolkit/astrodb-bot/issues/102), which documents the same gotcha from the skill-user workaround side; this issue is for the actual template-data fix.

_Reported from a gotchas.md log filed by a skill user (2026-08-28)._

Start with data/reference/PhotometryFilters.json, then compare every telescope and instrument referenced there with data/reference/Telescopes.json and data/reference/Instruments.json. Add the missing Paranal and VISTA rows and audit the other shipped filter references; done means each referenced telescope and instrument has a matching row and the reported Paranal ingestion no longer fails.
