Changelog: 4 entries

[ArthurMayoux]

Adds 4 new changelog entries:

1. Search Third Parties by Name — Find a third party by name instead of scrolling through the full register. Name search makes it quicker to locate a vendor record and continue reviewing its details.
   File: src/content/changelog/2026-09-30-search-third-parties-by-name.mdx
2. Filter Tasks by Assignee — Narrow organization and measure task lists to the person responsible. Former members remain available in the filter, so assignments stay findable after someone leaves the team.

3. Identity Settings, Reorganized — SAML and SCIM now have separate settings sections, with dedicated SAML setup pages, clearer enforcement choices, visible DNS verification details, and a paginated SCIM event history.
