chore(conf): revert seed defaults to stock so fresh installs auto-connect

The previous seed pinned auth/realmlist to production values
(`hsrwow.net` + RealmServerPort 47497), which silently bricked every
fresh local install: after auth login the realm hand-off pointed
clients at our public host, where their local credentials don't
exist, and they were dropped within a frame.

Seed now matches stock AzerothCore for solo dev:
- realmlist.address  = 127.0.0.1   (was hsrwow.net)
- RealmServerPort    = 3724        (was 47497)

Production owners apply both overrides post-dbimport via a one-shot
SQL UPDATE + an authserver.conf edit. Documented end-to-end in
contrib/fractured-dev-extras/BUILD-NATIVE.md (new "Production
deployment overrides" section) and the disconnect-after-login
symptom is called out in CLIENT-PATCHES.md.

 ## Fractured client + network defaults
 
-Production Fractured uses a non-default **auth** port so the client realmlist can be:
+Stock-friendly defaults for fresh local installs. A `git clone` ->
+`docker compose up` (or native install) lets a single developer log in
+from the same machine without any post-install config tweaks.
+
+- **`authserver.conf` -> `RealmServerPort`** = **3724** (stock WoW). A
+  patched `Wow.exe` with `set realmlist 127.0.0.1` (no port) reaches
+  the auth handshake.
+- **`realmlist` table -> `port`** is the **world** port (default
+  **8085**, matches `WorldServerPort` in `worldserver.conf.dist`).
+  Auth tells the client to handshake to this port for the world hand-off.
+- **`realmlist` table -> `address`** defaults to **`127.0.0.1`** in the
+  base SQL. The auth server hands this address to clients after login,
+  so 127.0.0.1 means "talk to the world server on the same machine
+  auth is running on" -- correct for solo dev. **Override on production
+  deploys**, see *Production deployment overrides* below.
+
+### Production deployment overrides
+
+Production Fractured runs on a remote VPS at `hsrwow.net` with auth
+bound to a non-stock port (47497 -- 3724 was unavailable on that host).
+Apply the overrides **once per fresh dbimport** on the production box.
+
+```sql
+-- Run against acore_auth on the production database after first dbimport:
+UPDATE realmlist
+   SET address = 'hsrwow.net',
+       port    = 8085          -- world port; leave at 8085 unless changed
+ WHERE id = 1;
+```
+
+Edit the production `authserver.conf` (NOT `authserver.conf.dist`)
+to bind the auth listener to the production port:
+
+```ini
+RealmServerPort = 47497
+```
+
+Restart the auth server. Production clients connect with:
 
 ```text
 set realmlist hsrwow.net:47497
 ```
 
-(Patched 3.3.5 clients that support `host:port`; otherwise use port forwarding to **3724**.)
-
-- **`authserver.conf` → `RealmServerPort`** must be **`47497`** (matches `authserver.conf.dist` in this repo).
-- **`realmlist` table → `port`** is the **world** port (default **8085**, same as `WorldServerPort` in `worldserver.conf.dist`), **not** 47497.
-- **`realmlist` → `address`** defaults to **`hsrwow.net`** in base SQL; change if your public hostname differs.
+The Fractured-patched 3.3.5 client supports the `host:port` syntax;
+stock 3.3.5 clients do not, so any contributor distributing the
+client bundle for production must include the patched `Wow.exe` from
+the GitHub release.
