Add credential recovery script, docs, and Redis wait

Introduce an interactive credential recovery tool (scripts/recover-credentials.js) and accompanying documentation (documentation/admin-features/credential-recovery.md). Add npm script rmab:recover to package.json and wire the doc into TABLEOFCONTENTS.md. Improve docker/unified/app-start.sh to wait for local Redis to finish loading before initializing app services to avoid "LOADING" errors when queues start. The recovery script uses Prisma, runs entirely interactively via docker exec -it, performs DB changes in a single transaction, and persists a rotated CONFIG_ENCRYPTION_KEY to /app/config/.secrets and /etc/environment when needed.

+# Credential Recovery Script
+
+**Status:** ✅ Implemented | Interactive recovery for lost `CONFIG_ENCRYPTION_KEY` or forgotten local admin password
+
+## Overview
+Recovers from the "Invalid username or password" failure mode caused by a lost or rotated `CONFIG_ENCRYPTION_KEY`. Detects whether the key still works; either does a minimal password reset (preserves everything) or full recovery (rotates key + clears credentials that can no longer be decrypted).
+
+## When to Use
+- Local admin gets "Invalid username or password" with credentials known to be correct
+- `/app/config/.secrets` was lost, truncated, or recreated
+- After an unintended `CONFIG_ENCRYPTION_KEY` change
+- See GitHub issue #200 for the symptom pattern
+
+## How to Run
+```
+docker exec -it <container-name> npm run rmab:recover
+```
+- `-it` is required for the interactive prompts
+- Or directly: `docker exec -it <container-name> node /app/scripts/recover-credentials.js`
+
+## What It Does
+1. Loads `DATABASE_URL` and `CONFIG_ENCRYPTION_KEY` from env (falls back to `/etc/environment`)
+2. Diagnoses key health by attempting to decrypt an existing encrypted Configuration row
+3. Lists local users (`authProvider='local'`, not soft-deleted); prompts for one
+4. Prompts for new password twice (masked); validates length unless `ALLOW_WEAK_PASSWORD=true`
+5. Prints the exact plan (mode + what will be cleared); requires typing `confirm` verbatim
+6. Executes inside a single Prisma `$transaction`
+7. If key was rotated: writes new key to `/app/config/.secrets` and `/etc/environment`
+
+## Two Modes (auto-detected)
+
+**Simple Password Reset (key works):**
+- Only updates the chosen user's `authToken` (new bcrypt, re-encrypted)
+- No other data touched
+- No container restart needed
+
+**Full Recovery (key broken):**
+- Generates new `CONFIG_ENCRYPTION_KEY` (32 random bytes, base64)
+- For each `Configuration` row with `encrypted=true`: re-encrypts with new key if old decrypt succeeds, deletes the row if not
+- For `download_clients` JSON: re-encrypts each client password if possible, blanks it if not (URL/host/etc. preserved)
+- For all `User.authToken` values: re-encrypts if possible, clears if not (Plex/OIDC users re-OAuth on next login)
+- Overwrites target user's `authToken` with fresh bcrypt encrypted with new key
+- Writes new key to `.secrets` + `/etc/environment`
+- **Container restart required after this mode**
+
+## What Survives (Full Recovery Mode)
+- All requests + request history
+- Library mappings, organization templates, schedules, user accounts
+- Non-encrypted Configuration rows (paths, log level, backend mode, etc.)
+- Plex/OIDC users whose tokens decrypted successfully (no re-OAuth needed)
+
+## What User Re-enters After Full Recovery
+- Plex auth token (or re-OAuth via login)
+- Audiobookshelf API token (if used)
+- OIDC client secret (if used)
+- Prowlarr API key
+- Download client passwords (per client)
+- Any AI / Hardcover / Goodreads / notification provider secrets
+
+## Security
+- CLI only — no HTTP endpoint, no auto-run, no rescue-mode env flag
+- Requires `docker exec` access (= host root equivalent)
+- Refuses to accept any CLI arguments — all input via interactive prompts
+- Does not echo or log password or key values
+- Operation summary written to stdout; full audit info to app logger
+- Idempotent within a single mode (re-runs are safe)
+
+## Failure Modes
+- DB transaction fails → no changes committed, safe to re-run
+- DB transaction commits but `.secrets`/`/etc/environment` write fails → script prints the new key in plaintext with instructions for manual write (one-time exposure in operator's terminal)
+
+## Related
+- `backend/services/auth.md` — local auth flow + the decrypt-then-compare path
+- `backend/services/config.md` — encryption format details
+- `deployment/unified.md` — entrypoint behavior and `.secrets` persistence
