P1 polish: Host.default_paths interim + restic env hygiene + job_id JS quoting

Two fixes that close the loop on dashboard run-now and harden the
agent's restic invocation.

Default paths (interim until P2-01 schedules):
  - 0003 migration adds default_paths TEXT NOT NULL DEFAULT '[]'
    to hosts and to enrollment_tokens.
  - Operator types paths in the Add-host form (textarea, one per
    line). They ride on the enrol_token row alongside the
    encrypted creds (paths aren't secret — plain JSON column).
  - On consume, ConsumeEnrollmentToken still just burns the token;
    the new GetEnrollmentTokenAttachments returns both the
    re-bindable creds and the path list in one round trip, the
    handler transfers them onto the new host row inside CreateHost.
  - The dashboard's Run-now and host-detail's "Run backup now"
    button now read Host.DefaultPaths and pass them to dispatchJob.
    A host with no default paths returns 400 with a friendly
    "no paths set" message instead of dispatching a doomed
    `restic backup` with no positional args.
  - Doc comments explicitly call this out as a Phase 1 interim —
    schedules supersede.

Restic env hygiene:
  - envSlice() previously omitted HOME / XDG_CACHE_HOME, which
    bit the smoke runs whenever the agent was launched outside
    systemd (restic refused to start: "neither $XDG_CACHE_HOME
    nor $HOME are defined"). Now both are set explicitly: prefer
    Env.ExtraEnv overrides, fall back to the agent process's own
    HOME, and finally to /var/lib/restic-manager.
  - Comment makes the env policy explicit: parent's RESTIC_* /
    AWS_* / B2_* env is filtered out by design — control-plane
    is the unambiguous source of truth.

JS bug fix in the live log page:
  - {{$job.ID | printf "%q"}} produced a literal-quoted JS string,
    which then went into the WS URL as ".../jobs/"<ID>"/stream"
    → 404. Switched to '{{$job.ID}}' inside the literal so
    html/template's auto-escape does the right thing. Verified
    end-to-end: dashboard "Run now" → live progress + log lines
    arrive over the WS → succeeded pill renders.
