Sweep hardcoded *.ocortez.com data URLs to HF resolve URLs (doc generators, analysis examples, index.html)

[oskrgab]

What to build

Point every consumer-facing and example data URL at the HF resolve base instead of *.ocortez.com, so copy-paste queries work against the new data host (ADR-0005). Prefer deriving URLs from BASE_URL over hardcoding.

Surfaces to update:

• scripts/export/petrobras_3w/schema_doc_generator.py (access-pattern example queries / source_url docs)
• scripts/export/force_2020/schema_doc_generator.py (BASE_URL = https://dev-petrodb.ocortez.com/force_2020)
• scripts/analysis/force_2020/plot_well_logs.py (BASE_URL = https://dev-petrodb.ocortez.com/force_2020/wells)
• scripts/analysis/argentina/production_analysis_remote.py and ..._imperial.py (BASE_URL = https://petrodb.ocortez.com/argentina)
• parquet/index.html — example DuckDB queries / data links

Schema docs/example queries must use manifest-based discovery (_files.json) against HF, never .../*.parquet globbing (ADR-0004). Leave the constants.py dev fallback host as-is (local Caddy dev is unchanged).

Acceptance criteria

• No data-fetching URL in the listed files points at *.ocortez.com; all use the HF resolve base (ideally via BASE_URL)
• Generated schema docs (schema.md) example queries copy-paste into DuckDB and succeed against HF
• parquet/index.html example queries reference HF resolve URLs and work
• Manifest-based discovery is used in examples (no *.parquet globbing)

Blocked by

• CI uploads parquet data to Hugging Face on push (data path tracer bullet) #37

Context: ADR-0005, ADR-0004 (manifest is the discovery contract). The dev-only Caddy fallback in constants.py stays unchanged.

Scope clarifier (no change to this issue)

With the landing moving to sumpalabs.com/petrodb (#38, ADR-0006), two different "base URLs" now coexist — keep them separate here:

• Data URLs (source_url, example DuckDB queries, doc-generator output) → the HF resolve base. That is the entirety of this issue's scope and is unchanged.
• Landing host (the human-facing page link, HF card, canonical/og:url) → https://sumpalabs.com/petrodb/. Not in scope here — handled in Slim the Cloudflare deploy to landing+docs and stage under /petrodb/ for sumpalabs.com #38.

So when sweeping index.html: repoint the dev-petrodb.ocortez.com/... query snippets to HF (this issue); leave any landing self-reference / canonical to #38.
