Align p2ns with current Holepunch ecosystem versions: autopass 3,
hyperdb 6, hyperschema 1.21, hyperdrive 13, corestore 7.10, hyperswarm
4.17, protomux 3.11, and compact-encoding 3 (with npm overrides).
Also bump Tailwind/PostCSS, ws, node-forge, and related tooling; add
express and holesail-logger; remove unused install/npm packages.
Use cache/plugin-spec when plugin spec dirs are not writable, and
update docs and proxy install notes. Rebuild admin CSS for Tailwind 4.3.
Existing P2P storage must be wiped (--clean) after upgrading.
