build(scripts): convert the last 14 standalone .mjs scripts to real .ts

Closes out the scripts/ TypeScript migration this branch's base commit
started: every remaining scripts/*.mjs file that had no paired .d.mts
(so wasn't covered by the prior "convert every .mjs/.d.mts pair"
commit) is now real .ts, type-checked against its actual behavior
instead of running untyped. Covers the actionlint/build-selfhost/
check-migrations/compute-test-shards/rees-coverage/smoke-observability-
{metrics,traces}/smoke-ui-browser/check-{mcp,miner}-package/
check-mcp-release-candidate/check-orb-{release,stable-release}-due/
check-changelog families.

Every consumer updated to match: package.json scripts, GitHub
workflows (orb-beta-release, orb-stable-release-pr, publish-miner,
release-selfhost, selfhost, test-timing-refresh), the Dockerfile and
.dockerignore, deploy-selfhost-prebuilt.sh, and comment-only references
across src/queue/processors.ts, packages/loopover-engine's deny-hooks,
the selfhost stub files, and the self-hosting docs pages. A script
invoked directly as a subprocess (not a same-directory .ts import)
keeps plain `node --experimental-strip-types`; one that imports another
local .ts file (e.g. check-orb-release-due.ts importing
orb-release-core.ts) needs tsx instead, since only tsx -- not node's
native strip-types -- resolves a `.js`-suffixed specifier to a sibling
.ts transitively.

Real invocations verified for every converted script against this
repo's own state (migrations, git tags, the packed npm tarballs, a
live loopover.ai smoke check, actionlint/composite-action lint), not
just typecheck -- including reproducing rees-coverage.ts's one
pre-existing, already-tolerated (`|| true` in ci.yml) analyzer-metadata
ENOENT quirk against the original .mjs to confirm it predates this
conversion rather than being introduced by it.
