[client] Categorize privileged tests behind a build tag and run them in Docker (#6425)

* [client] categorize root/system-mutating tests behind a privileged build tag

Tests that need root or mutate host state (nftables/iptables/DNS, TUN/WireGuard
interfaces, routes, eBPF, SSH/service install) are now gated behind a
//go:build privileged tag. The default `go test ./client/...` runs as a non-root
user with no sudo and leaves host networking untouched; mixed files were split so
pure-logic tests stay in the default suite.

A self-hosting ory/dockertest/v4 harness (client/testutil/privileged) runs the
privileged suite inside a --privileged --cap-add=NET_ADMIN container via
`make test-privileged`; a DOCKER_CI=true guard skips the spawn when already inside
the container. Added `make test-unit` for the host-safe run.

* [client] add PRIV_RUN/PRIV_PKGS filters to the privileged test harness

The dockertest harness now reads two optional env vars when building the
in-container `go test` command: PRIV_RUN adds a -run test-name filter and
PRIV_PKGS overrides the package list. Both empty reproduce the full privileged
suite, so CI and `make test-privileged` behave as before. Lets a developer run a
single privileged test in the container, e.g.:

  PRIV_RUN=TestNftablesManager PRIV_PKGS=./client/firewall/nftables/... make test-privileged

* [client] fix unused-helper lint after the privileged test split

Splitting privileged tests into *_privileged_test.go left their shared helpers in
the untagged files, so in the default (no-tag) build they had no callers and
golangci-lint flagged them as unused.

Moved the privileged-only helpers into the privileged files next to their callers
(generateDummyHandler; createEngine/startSignal/startManagement/getConnectedPeers/
getPeers + kaep/kasp; (*mockDaemon).setJWTToken). Annotated the shared routing-test
fixtures that must stay untagged for cross-platform compilation with //nolint:unused
(systemops_bsd expected* vars, ensureIPv6DefaultRoute on bsd/windows,
loopbackIfaceWindows), matching the existing linux variant.

* [client] fix privileged test CI failures and run the harness on macOS

The host-safe unit run dropped sudo but two privileged test groups were
never tagged, and the Docker privileged job silently never ran the suite:

- Gate the ssh/server PrivilegeDropper command-construction tests behind
  the privileged tag (they require root to target a different UID); split
  them into executor_unix_privileged_test.go.
- Tag sharedsock raw-socket tests privileged (need CAP_NET_RAW).
- Fix the Docker job command: nested single quotes around the build tags
  closed the sh -c wrapper early, dropping the go list package set and the
  privileged tag, so go test ran on the empty repo root. Use double quotes.

Make the self-hosting harness usable from a dev Mac:

- Build it on darwin as well as linux; it only drives Docker.
- Resolve the active docker context endpoint into DOCKER_HOST when the
  default /var/run/docker.sock is absent (Docker Desktop, Colima, OrbStack).
- Rename the misspelled containerGoModache constant to containerGoModCache.

* [ci] Run privileged-tagged tests on darwin, windows and freebsd

The privileged build tag split moved root/system-mutating tests behind
//go:build privileged, but only the linux docker job was given the tag.
The native darwin (sudo), windows (PsExec64 -s) and freebsd VM runners
already have the required privileges, so add the privileged tag there too
to keep CI running the same set of tests as before the split.

* [ci] Exclude dockertest harness from the darwin privileged run

The privileged tag now compiles client/testutil/privileged on darwin, whose
TestRunPrivilegedSuiteInDocker spawns a container the macOS runner has no
Docker for. Exclude the harness package from the darwin list, matching the
linux job, so the privileged tests run in place without a container spawn.
