docs(limits): integrate In-App/OSM/Cards limits in-context (§13, §14)

[mallikarjun-dhulange]

Platform limits — In-App / OSM / Cards POD

Integrates the In-App, On-Site Messaging, and Cards platform limits (Confluence §13 + §14) into the docs, in context. No snippets, no hub. Confluence is the source of truth for this work.

Gaps filled in-context (§13 In-App/OSM)

• Active In-App/OSM campaigns per workspace = 200 → overview-in-app-message.mdx
• Re-evaluate campaign eligibility = max 5 campaigns → create-in-app-campaign.mdx
• App contexts per "On screen load" trigger = 5 → create-in-app-campaign.mdx
• FC rules = 10 total, incl. 3 tag-based → frequency-capping.mdx
• Nudges per screen = 3 and video nudge max = 10 MB → html-nudge-templates.mdx

Verified already-documented (no change needed)

§13: screens per trigger 5 · After Delay 1 day (86,400 s) · "AND then" wait 24 h · A/B variations 5 · locales 11 · native image 10 MB.
§14 Cards: header 30 / message 115 chars · image/GIF 10 MB · card expiry 180 days · auto-sync 45 min · inbox refresh 5 min · pull-to-refresh 5 s · analytics unique window 72 h.

Deferred / flagged (see PR comment)

• Cards Fetch API & Delete API rate = 50K RPM → API POD (API-surface).
• Meta-call refresh (15 min) and self-handled In-Apps per trigger (5) → SDK behaviours; likely belong in the mobile SDK docs, not user-guide.
• "Max active cards at a time" — value is blank in Confluence §14; nothing to publish until a PM fills it.

Notes for review

Deferred to the API POD: Cards Fetch API and Delete API rate limits (50K RPM each) are API-surface limits and will land on the api/ Cards pages in the API POD PR.

Likely SDK-doc material (not user-guide): two §13 limits are pure SDK runtime behaviours with no natural user-guide home —

• Meta-call refresh interval (15 min) — how often the SDK re-fetches eligible In-App campaigns.
• Max self-handled In-Apps per single trigger (5) — the SDK returns the top N in priority order.

These read better in the mobile SDK integration docs. Flagging for a home decision rather than forcing them onto a dashboard page.

Blank in Confluence: §14 "Max active cards at a time" has no value filled in — nothing to publish until the PM completes that row.
