PR Summary

Medium Risk
Tailscale/tsnet underpins authz VPN connectivity; a two-minor-version jump can affect networking behavior even without local code edits.

Overview
Bumps tailscale.com from 1.98.5 to 1.100.0 and refreshes go.sum. The module go line moves from 1.26.3 to 1.26.4 to align with the new Tailscale release.

Transitive pins pulled in with the upgrade include github.com/tailscale/wireguard-go, golang.org/x/crypto (0.51.0 → 0.52.0), github.com/go-json-experiment/json, golang.org/x/image, and github.com/go4org/hashtriemap. No application source files change; authz still uses tailscale.com/tsnet as before.
