chore: resolve remaining repository checker findings

[DutchmanNL]

Second wave of ioBroker repository checker cleanup, against the current body of #136.

Codes fixed

Code	Fix
E0040	"ioBroker" added to package.json keywords
E0063	removed chai, chai-as-promised, mocha, sinon, sinon-chai and their @types from devDependencies (bundled by @iobroker/testing v5)
E1027 / E1034 / E1054	Ukrainian (uk) added to common.titleLang, common.desc and both common.news entries
E5010 / W5603	new admin/i18n/uk/translations.json
E1057	js-controller >=6.0.11, admin >=7.6.20
E4041	io-package.json schema URL corrected in .vscode/settings.json
W4042	jsonConfig schema mapping added to .vscode/settings.json
E5005	this.setTimeout() / this.clearTimeout() for the data-refresh timers
E5043	node:crypto, node:https, node:util
E5509 / E5510	interval number fields now use xs 12 >= sm 6 >= md 4 >= lg 3 >= xl 2; all six items were adjusted, so the truncated E5510 list should be covered
E5612	"Secret Key" label key added to every admin/i18n/*/translations.json
E6026 / E6029 / W6027 / W6030	## Support me moved above ## Changelog so the ### version entries (including 0.1.2) sit inside the changelog section again; the stray ### coming soon heading folded into ### __WORK IN PROGRESS__
E9006	.commitinfo added to .gitignore
W5047	legacy admin UI removed (admin/index_m.html, admin/style.css, and the now-orphaned admin/words.js)
W5057 / W5058	secretKey declared in native, protectedNative and encryptedNative
W6023	standard Sentry notice added near the top of README.md

Extra (not a checker code): typescript bumped to ^5.9.3 and types: ["node", "mocha"] restored in tsconfig.check.json — npm run check was failing on main with 6 errors (TS 4.9 cannot parse the lib entries of @tsconfig/node22) and is now clean.

Bot issues

#137 (Node.js 24) and #138 (@iobroker/adapter-core) are satisfied by the current main and have been closed. #135 (ESLint 9 / @iobroker/eslint-config) is also already implemented and was closed.

Leftovers

Code	Why
W3009 / E3009	the concurrency: block deliberately deviates from upstream: release runs triggered by a tag are never cancelled, because cancelling them aborts the deploy job and leaves a half-finished release (which the checker then reports as W3032). Accepted, documented deviation.
E2008	npm provenance / trusted publishing — needs an action on npmjs.com, not in the repo
E3032 / W8005	only clears once a new release is cut and the tag workflow run exists
W4001	adapter is not in the ioBroker latest repository yet — needs a PR to ioBroker.repositories
W0076	prettier.config.mjs is missing. Adding it activates the ioBroker prettier ruleset inside eslint, which turns the whole code base into ~985 lint errors (4-space indent / single quotes vs. the current prettier defaults). That is a mechanical eslint . --fix reformat, but it would bury this PR under a ~1000 line diff, so it is left for a dedicated formatting commit.
W6020	CHANGELOG_OLD.md — optional, only 3 released versions so far
S5601	short i18n format ({lang}.json) — optional migration

Local verification

• npm install --no-audit --no-fund (clean tree, lockfile regenerated) — ok
• npm run lint — 0 errors, 5 pre-existing jsdoc warnings
• npm run check — clean (was 6 errors on main)
• npm run test:package — 57 passing
• npm run test:js — 1 passing
• npm run test:integration — 1 passing, adapter starts and terminates cleanly on js-controller 7.2.3 / Node 24
