fix(docs): pin quickstart to pre-PQC platform image and config

[marythought]

Problem

The quickstart docker-compose downloads opentdf-example.yaml from platform/main, which now includes hybrid PQC keyring entries (hpqt:xwing, hpqt:secp256r1-mlkem768, hpqt:secp384r1-mlkem1024) added in opentdf/platform#3276. The quickstart's generate-keys service only creates RSA and EC keys via openssl — no PQC key files are generated. The platform crashes at startup:

failed to read private key file [/keys/kas-xwing-private.pem]: no such file or directory

Confirmed main is broken: https://github.com/opentdf/docs/actions/runs/27036624683

Stopgap fix

Pin the platform image (nightly-a29f108) and config download to the last main commit before PQC landed. Image and config stay in sync, no PQC keys needed.

Long-term fix (add PQC key generation to the quickstart) will follow in a separate PR.

Fixes #336

Test plan

• BATS quickstart tests pass locally (23/23)
• CI docker-compose stack test passes on this branch
• CI docker-compose stack test fails on main (run)

📝 Walkthrough

Walkthrough

The docker-compose quickstart downloads a platform configuration file via wget. This change updates the source from opentdf-example.yaml to opentdf-dev.yaml to align the configuration with the key generation capabilities of the quickstart's inline keygen service.

Changes

Quickstart Config Alignment

Layer / File(s)	Summary
Docker-compose platform config source docs/getting-started/docker-compose.yaml	The download-platform-config service fetches opentdf-dev.yaml instead of opentdf-example.yaml. The dev config excludes PQC keyring entries, preventing key-not-found errors when the quickstart's RSA/EC-only keygen service runs.

Poem

A config so small, yet fixes the way,
Dev config chosen to save the day,
No PQC files to chase or to find,
RSA and EC leave trouble behind,
The quickstart hops forward with joy and delight! 🐰

332-340: ⚖️ Poor tradeoff

Consider pinning downloads to stable release tags for long-term stability.

All external file downloads currently reference the main branch (lines 339, 371, 415, 430), which makes the quickstart vulnerable to future breaking changes upstream. While the current change correctly fixes the immediate PQC key mismatch, a future enhancement could pin these downloads to stable release tags instead.

This would provide:

• Predictable, tested configurations
• Protection against breaking changes on main
• Easier rollback if issues arise

However, this is a broader architectural decision beyond the scope of fixing the current PQC key issue, and the current approach is consistent across all downloads.

Also applies to: 360-405, 408-416, 419-464

Confirmed main is broken — the stack test times out with the platform returning 502 for 5 minutes (the container crashes on the missing xwing key): https://github.com/opentdf/docs/actions/runs/27036624683

The same test passes here, which indicates that the quickstart guide should work when this is merged.
