[codex] Add Workflow Pause documentation

[JLDLaughlin]

What changed

• Added a new Workflow Pause concept page under Encyclopedia > Workflows.
• Linked the new page from the Workflow sidebar and Activity Operations page.
• Updated Workflow Execution status docs to include Paused as an Open status.

Why

Workflow Pause needs public Pre-release documentation that explains when to use Pause and Unpause, what behavior users should expect, observability, limitations, billing, and the relationship to Activity Operations.

Notes

• This is a fresh branch/PR retry for the same squashed content as [codex] Add Workflow Pause documentation #4729 because Vercel failed there without logs available to this user.
• This keeps Web UI content to support-surface/version wording only, matching the Activity Operations page pattern.
• This does not modify generated CLI docs or shared lint/formatting config.

Validation

• Ran git diff --check origin/main...HEAD.
• Manually checked internal links for CLI anchors, release stage, support ticket, List Filter, Schedule, Cron Job, Child Workflows, Activity Operations, Workflow Execution/Event History, and Active Storage pricing.
