fix(json): emit canonical camelCase JSON wire keys

[hortison]

Summary

Flips the remaining snake_case JSON output keys to camelCase across three theme templates, completing the canonical wire-tag contract for the academy JSON view files that meshery-cloud reads at runtime via LoadCurricula.

The hard prerequisite

layouts/partials/learning-path.json.html line 23 emits "org_id", which populates AcademyCurricula.OrgId in the cloud-side decode. The academy schema flipped this wire tag between v1beta2 (json:"org_id") and v1beta3 (json:"orgId"), and v1beta3 has no UnmarshalJSON fallback (confirmed against models/v1beta3/academy/zz_generated.helpers.go). Without this change, the planned meshery-cloud v1beta3 migration (layer5io/meshery-cloud#5379) would have every LoadCurricula silently write nil-OrgId rows and break org-scoped curriculum lookups.

Adjacent canonical-casing alignment (same PR)

Folded in per the maintainer-mindset rule (pay down adjacent debt while in the area). Every JSON output key the theme emits is now canonical camelCase:

File	Snake -> camel
layouts/partials/learning-path.json.html	org_id, total_courses, total_tests, total_modules, total_pages, prerequisite_knowledge, related_resources, additional_attributes
layouts/partials/common-curricula-properties.html	reading_time, prerequisite_knowledge, related_resources
layouts/lab/single.json.json	starter_catalog_link, starter_embed_link, answer_catalog_link, answer_embed_link

The quiz template (layouts/partials/test/single.html) was already camelCase; this PR brings the remaining three to parity. The build (layer5io/academy-build) must be re-run after merge to publish refreshed index.json artifacts before any cloud v1beta3 deploy.

What does NOT change

• Source-side reads (.Params.<snake_case>) are left untouched. They match existing frontmatter keys in the content repos (layer5io/layer5-academy, layer5io/exoscale-academy, meshery-extensions/meshery-academy, layer5io/academy-example). The transformation is purely on the JSON output side, so no content repo requires any change for this migration.
• Hugo template logic, variable expressions, or any structural code. The diff is +15/-15, exclusively the string literals inside the JSON object keys.

Test plan

This is a pure string-literal change to JSON-emitting Hugo templates. Hugo template parsing is unaffected by string content. Verification:

• grep -rnE '"[a-z]+_[a-z_]+":' layouts/ --include='*.html' --include='*.json' returns empty post-edit (zero residual snake_case JSON output keys across the theme). Confirmed locally.
• Reviewer to confirm via a Hugo build against a content site (e.g. layer5-academy or academy-example), then inspect public/learning-paths/index.json for orgId (camelCase) and absence of org_id. Local Hugo build was attempted but the docsy transitive module resolution conflicted with the local-replacements env var setup; the change is mechanical enough that a CI-driven build verification is the appropriate gate.
• Downstream verification: meshery-cloud's planned v1beta3 academy PR (Phase 1 of meshery-cloud#5379) confirms LoadCurricula writes non-nil OrgId rows.

Pull request overview

This PR standardizes the JSON “wire” keys emitted by the academy theme’s JSON templates by converting remaining snake_case output keys to canonical camelCase, aligning with the v1beta3 academy schema expectations used by meshery-cloud’s LoadCurricula.

Changes:

• Updated learning-path.json.html to emit orgId and camelCase aggregate/metadata keys (e.g., totalCourses, prerequisiteKnowledge).
• Updated common-curricula-properties.html to emit camelCase keys (e.g., readingTime, relatedResources).
• Updated the lab JSON output (single.json.json) to emit camelCase link keys (e.g., starterCatalogLink, answerEmbedLink).

Code Review

This pull request updates several Hugo template files, including layouts/lab/single.json.json, layouts/partials/common-curricula-properties.html, and layouts/partials/learning-path.json.html, to convert JSON output keys from snake_case to camelCase. Specifically, keys such as starter_catalog_link, reading_time, org_id, and various total_ count fields have been renamed to their camelCase equivalents. I have no feedback to provide.
