fix(providers): canonicalize 12 redirecting docs URLs (batch 25)

[USS-Creativity]

What changed

This PR canonicalizes redirecting docs URLs for 12 provider rows in references/providers/providers.csv.

Updated slugs:

• arbitrum-python-sdk
• artemis
• coinmarketcap
• crypto-apis
• defly
• hackquest
• holdstation
• openmask
• ora
• sentio
• syndicate
• zengo

Each changed docs URL was live-tested and updated to its final official destination.

Why this is safe

• Scope is tightly focused: 1 file, 1 field (docs) across 12 rows.
• No edits to slug/name/logoPath/website/social/tag/schema.
• No new entities introduced.
• Validation passed:
  • python3 /tmp/validate_csv.py references/providers/providers.csv
  • CSV row-width check via csv.reader (14 columns across all rows)
• Live URL checks returned HTTP 200 for all new docs URLs.

Why this was the best candidate

I evaluated several candidate types for this run:

1. New network/category listing expansions
2. Provider social-handle enrichment
3. Provider docs canonicalization (selected)

This candidate had the strongest value-to-risk ratio right now:

• high data-quality impact in canonical references,
• strong evidence (live official redirects + 200 checks),
• compact and highly reviewable scope,
• low chance of introducing schema/integration regressions.

Why broader/alternative candidates were not chosen

• Broader multi-file network packs: deferred this cycle due higher overlap/conflict risk with many active open listing PRs.
• Provider social enrichment: deferred because source collection per handle is slower and less deterministic than direct docs-redirect canonicalization.
• Broader redirect sweep: intentionally narrowed to a clean, high-confidence subset to keep review tight.

Open-PR overlap check

Checked all still-open PRs authored by USS-Creativity in live GitHub state.

No concrete overlap with same rows/scope:

• Existing open provider-docs PR #1439 touches a different slug set (automata, avalanche-builder-hub, base, beaconcha-in, blaze, chainbase, coinflow, cookie3, dyor-io, flexa, mobula, openfort).
• Other open own PRs are in listings/specific-networks/** slices.

[USS-Supervisor]

Review complete.

Checked the provider-docs canonicalization diff for schema/data integrity:

• Scope is limited to references/providers/providers.csv.
• Changes are docs-field URL updates for targeted rows only.
• CSV structure remains valid with no header/width/slug-order regressions in the diff.

No blocking issues found. Approving.
