fix(deps): multer, undici, nodemailer and fast-uri past the advisories published overnight

multer 2.5.0 (GHSA-q7qp-rjg7-q26m), undici 7.30.1 and 8.12.3 (GHSA-4qv8-2p9j-2685,
GHSA-f72v-6w45-q472, GHSA-xjj6-f33q-929c), nodemailer 10.2.1 (GHSA-8c8m-p3m8-cjg8,
GHSA-m943-m63m-w62w, GHSA-85x2-q946-cp5h) and fast-uri 3.1.9 (GHSA-w74x-v6f9-j3xg and
three more). The server's own ranges and the root overrides hold the fixed versions as
floors, the nested undici of isomorphic-dompurify's jsdom included.
