feat(P7): doctor ingress + docs + integration tests (REQ-177,178,179)

New 'orca doctor ingress' command: verifies podman orca-traefik
container running, nft DNAT+SNAT, /etc/traefik/dynamic exists,
step-ca root CA present.

UAT signoff script: replaced assertion 36 (systemd → podman
container), added assertions 40-46 (nft table, DNAT, SNAT, dynamic
dir, step-ca CA, traefik.yml, doctor ingress pass).

docs/ingress.md: R-024 podman traefik section — three topologies,
container config, nft ruleset, doctor ingress, Dockerfile.traefik.
TLS model updated (drop certResolver, tls:{} for v0.14, mTLS v0.15).

ARCHITECTURE.md: v0.14 deltas section — R-024, three topologies,
nft emitter changes, TLS model, migration 0009, new CLI.

Integration tests (tests/ingress_bootstrap_test.go): nft postrouting
+ DNATTarget, priority -10, traefik TLS model (tls:{} no
certResolver), image ref resolution, floating-IP LXC provisioning
commands (pct create with hwaddr/ip/gw/features), MAC generation.

+## v0.14 Deltas — Ingress Bootstrap Completeness (R-024)
+
+### R-024: Traefik as Podman Container
+
+Traefik runs exclusively as a podman container, deployed from the
+custom `orca-traefik` image (published per release via `Dockerfile.traefik`
++ `scripts/release.sh` + `.coreci.yml container-publish-traefik`).
+
+The v0.13 binary+systemd install (`internal/traefik/install.go`) is
+replaced by an idempotent podman container reconciler
+(`EnsureTraefikContainerLocal`/`Remote`). The container runs with
+`--network host`, `--restart=unless-stopped`, and volume mounts for
+`traefik.yml` (static config), `dynamic` (dynamic config), and
+`step-ca-root.crt` (future mTLS). No SELinux `:Z` flag.
+
+### Three Ingress Topologies
+
+1. **Linux** (`orca init` / `orca node join --type linux`):
+   host → nft DNAT → podman traefik (host network).
+   `internal/ingress/bootstrap.go` → `BootstrapLocalIngress` /
+   `BootstrapRemoteIngress`.
+
+2. **Proxmox Native** (`--ingress-mode native`, default):
+   PVE host → nft DNAT (target = LXC bridge IP) → LXC
+   (`--features nesting=1,keyctl=1,fuse=1`) → podman traefik.
+   `internal/proxmox/bootstrap.go` → `provisionNativeIngressLXC`.
+
+3. **Proxmox Floating-IP** (`--ingress-mode floating-ip`):
+   LXC owns the floating IP (`net0 bridge=vmbr0,hwaddr=<mac>,
+   ip=<floating-ip>/<prefix>,gw=<gateway>`) → nft inside LXC →
+   podman traefik. The ingress LXC is registered as a `linux` node
+   (name=`ingress`) so `orca job run` pushes traefik dynamic config.
+   `internal/proxmox/ingress_lxc.go` → `ProvisionIngressLXC`.
+
+### nft Emitter Changes
+
+`internal/emitter/nft.go`:
+- `DNATTarget` field (C-51: validated via `net.ParseIP`). Default
+  `127.0.0.1`; proxmox native uses LXC bridge IP.
+- `EnableSNAT` field + postrouting masquerade chain: `ip saddr
+  127.0.0.0/8 oifname != "lo" masquerade` (research Topic 1).
+- Input/forward chain priority shifted from `filter` (=0) to `-10`
+  (research Topic 2: pve-firewall coexistence — avoids same-priority
+  undefined evaluation order).
+
+### TLS Model
+
+v0.14 drops `certResolver: orca` from the dynamic config (traefik v3.3
+only supports `acme`/`tailscale` resolvers, not CA-file-based). The
+dynamic config emits `tls: {}` (traefik default cert). Real mTLS via
+`tls.certificates` + `tls.options.default.clientAuth.caFiles` is
+deferred to v0.15 (grill G-003, confidence 0.55 < 0.60).
+
+### Migration 0009
+
+`ALTER TABLE nodes ADD COLUMN ingress_mode TEXT NOT NULL DEFAULT '';`
+Values: `""` (legacy), `"native"`, `"floating-ip"`. `IngressMode` field
+on `model.Node`.
+
+### New CLI
+
+- `orca doctor ingress` — verifies podman container running, nft
+  DNAT+SNAT, dynamic dir, step-ca root CA.
+- `--ingress-mode` flag on `orca node join --type proxmox`.
+- `--floating-ip`, `--gateway`, `--mac`, `--net-prefix` flags for
+  floating-IP mode.

+## R-024: Podman Traefik Container (v0.14)
+
+As of v0.14, Traefik runs as a **podman container** from the custom
+`orca-traefik` image (published per release). The v0.13 binary+systemd
+install is replaced.
+
+### Three topologies
+
+1. **Linux**: host → nft DNAT → `podman run orca-traefik` (`--network host`)
+2. **Proxmox Native** (`--ingress-mode native`, default): PVE host →
+   nft DNAT → LXC (nesting=1,keyctl=1,fuse=1) → `podman run orca-traefik`
+3. **Proxmox Floating-IP** (`--ingress-mode floating-ip`): LXC owns
+   the floating IP → nft inside LXC → `podman run orca-traefik`
+
+### Container configuration
+
+```bash
+podman run -d --name orca-traefik --restart=unless-stopped \
+  --network host \
+  -v /etc/traefik/traefik.yml:/etc/traefik/traefik.yml:ro \
+  -v /etc/traefik/dynamic:/etc/traefik/dynamic:ro \
+  -v /etc/orca/step-ca-root.crt:/etc/orca/step-ca-root.crt:ro \
+  git.cloudinit.dev/coreci/orca-traefik:<version>
+```
+
+- `--network host`: traefik binds 127.0.0.1:8080/8443 on host/LXC loopback
+- `--restart=unless-stopped`: survives reboot via `podman-restart.service`
+- No `:Z` SELinux flag (research Topic 7)
+- Static config mounted `:ro` (overrides baked image default, preserves
+  `traefik-on-public-ip` opt-out, REQ-100)
+
+### nft ruleset
+
+The nft emitter (`internal/emitter/nft.go`) renders `/etc/nftables.d/orca.nft`:
+
+- DNAT `:443` → `<DNATTarget>:8443` (default 127.0.0.1; LXC IP for native)
+- DNAT `:80` → `<DNATTarget>:8080`
+- SNAT/MASQUERADE: `ip saddr 127.0.0.0/8 oifname != "lo" masquerade`
+- Input/forward chains at priority -10 (pve-firewall coexistence)
+
+### `orca doctor ingress`
+
+```bash
+orca doctor ingress              # check localhost
