feat(post_analysis_to_slack): make details URL a {vcon_id} template

[ScottHenshaw86]

Summary

• The Slack details URL was hard-coded as ?_vcon_id="<uuid>", which works for Hex but not for path-based destinations like our reporting portal.
• The url config option is now a template: if it contains {vcon_id}, the uuid is substituted there — letting each destination own the placement and quoting.
• URLs without {vcon_id} fall back to the legacy ?_vcon_id="<uuid>" suffix, so existing Hex configs keep working unchanged.

Examples:

# Hex sheet — uuid wrapped in double quotes inside a query param.
url: 'https://app.hex.tech/<workspace>/app/<app>/latest?_vcon_id="{vcon_id}"'

# Portal — uuid embedded raw in the path.
url: "https://portal.strolidcxm.com/app/conversations/{vcon_id}"

Test plan

• poetry run python -m pytest conserver/links/post_analysis_to_slack/test_post_analysis_to_slack.py — all 7 tests pass (4 new + 3 existing)
• Smoke test the Hex config in a non-prod environment to confirm legacy fallback still emits the same URL
• Update the production config to use the {vcon_id} template form for the portal rollout

Pull request overview

This PR updates the post_analysis_to_slack link so the configured “details” URL can be treated as a template, enabling path-based destinations (e.g., portals) while preserving legacy behavior for existing Hex-style configs.

Changes:

• Added build_details_url() to render details URLs via {vcon_id} substitution, with a legacy fallback that appends ?_vcon_id="<uuid>".
• Updated the link runtime to use build_details_url() instead of hard-coding the query suffix.
• Added/updated documentation and tests covering the template behavior.
