[npm] Bump @types/node to ^26.1.1 across client, client-v3, electron (#1293)

* [npm] Bump @types/node to ^26.1.1 across client, client-v3, electron

typescript stays on ^6.0.3 for now: typescript-eslint@8.63.0's peer range
(>=4.8.4 <6.1.0) blocks TypeScript 7, and TS 7.0 doesn't ship a compiler
API yet, so bumping it would break ESLint's type-aware linting in CI.

* Fix electron lockfile drift causing npm ci failure in CI

The initial npm install left the encoding/iconv-lite optional peer
dependency (pulled in transitively by minipass-fetch) out of the lock
file, so npm ci failed with EUSAGE on CI. Regenerating package-lock.json
from scratch (not just node_modules) restores it.
