fix(deps): clear remaining npm audit advisories (#2075)

Adds overrides for the five advisories present in the production
dependency tree, plus two dev-only stragglers, bringing `npm audit`
to zero.

Only ip-address is meaningfully reachable: server/src/index.ts builds
sandboxRateLimiter from express-rate-limit, which parses IPs via
Address6 for subnet keying. Impact here is a rate-limit key bypass on
/sandbox rather than the SSRF the advisory titles imply, since req.ip
derives from the socket and the proxy binds localhost.

The other four are installed but unexercised: hono middleware is never
wired up, @hono/node-server's serve-static is never imported (only
getRequestListener), fast-uri is reached only for ajv format checks
whose result is never trusted for a host decision, and brace-expansion
expands serve-handler's config-supplied pattern rather than the
attacker-supplied path. nanoid and postcss are dev-only.

Every patched release exists within the current major line.
@hono/node-server is deliberately held at 1.19.17 rather than 2.x — a
major bump has no place on a deprecated branch.

Lock entries are patched in place rather than re-resolved, keeping the
diff to the affected packages.

Fixes #2074
