docs: combine the 22 pending release notes into one changelog update

[lucmir]

Summary

Combines all 22 pending release-notes PRs into one changelog update, so there's a single review and no conflicts between them.

• docs/civic/changelog.mdx — 8 entries (Civic / civic-mcp)
• docs/overview/changelog.mdx — 14 entries (Auth: auth-server and apps)

183 insertions, 0 deletions. No existing line is touched or moved.

How the entries were placed

Not stacked on top. Each of those PRs branched off the main of its day and inserted at the top of the file, so simply concatenating them would have produced a changelog in roughly reverse-random order. Both files are strictly newest-first, so each entry is inserted at its correct chronological position, interleaving with entries already merged. In the Civic changelog that reads:

v0.1.156  July 14   (new)
v0.1.155  July 10   (new)
v0.1.154  July 09   (already merged)
v0.1.153  June 30   (new)
v0.1.152  June 05   (already merged)
v0.1.151  June 01   (new)
v0.1.150  May 29    (already merged)

Entries already merged keep their exact relative order (stable sort by date), which is why the diff is pure insertion.

The legacy Mintlify-era entries at the bottom of both files — different header shape (tags={...}, "September 26th, 2025", "December 2025") and not reliably ordered — are left completely untouched: 3 in the Civic file, 18 in the Auth file. Only the modern date-ordered prefix was sorted.

Verified

• Diff is 183 insertions, 0 deletions, across the two files only.
• Both files re-parsed after the merge: 0 date-order violations (70 modern entries in Civic, 34 in Auth).
• No duplicate versions in either file, and none of the 22 versions was already present on main.
• Every source PR contributes exactly one <Update> block and touches exactly one file — checked before merging, so nothing else rode along.

Source PRs — safe to close once this merges

Not touched: #905, #899, #895 (not release-notes PRs).
