fix: navbar mobile dropdown clipped left edge - use left-0 instead of right-0

The dropdown was anchored to right-0 of the <details> element.
On mobile, the trigger button sits near the left side of the viewport
so right-0 caused the panel to extend leftward off-screen.
Changing to left-0 opens the panel rightward from the button, keeping
it fully visible.

+# Preuzimanje produkcijske baze podataka na lokalni PC
+
+Vodič za lokalni razvoj s kopijom produkcijskog PostgreSQL-a bez mijenjanja produkcijske baze.
+
+---
+
+## Preduvjeti
+
+- SSH pristup produkcijskom serveru
+- Docker Desktop instaliran lokalno
+- `scp` dostupan u PowerShell / terminalu
+- Lokalni `.env` s `DEBUG=True` i **drugačijim** `SECRET_KEY` od produkcije
+
+---
+
+## Korak 1 — Na produkcijskom serveru: napravi dump
+
+SSH-aj na produkcijski server, zatim pokreni:
+
+```bash
+docker exec 004erpdb pg_dump \
+  -U $POSTGRES_USER \
+  -d $POSTGRES_DB \
+  --no-owner \
+  --no-acl \
+  -Fc \
+  -f /tmp/prod_dump.dump
+```
+
+> **`-Fc`** — custom format (komprimiran, pogodniji za `pg_restore`)  
+> **`--no-owner --no-acl`** — izostavlja produkcijske usere i privilegije
+
+Ako env varijable nisu dostupne u shell sesiji, napiši vrijednosti direktno:
+
+```bash
+docker exec 004erpdb sh -c \
+  "pg_dump -U TVOJ_USER TVOJA_BAZA --no-owner --no-acl -Fc -f /tmp/prod_dump.dump"
+```
+
+Ako baza ima desetke gigabajta, pg_dump može opteretiti disk produkcije. U tom slučaju, dumpaj u komprimirani format **--exclude-table-data='log_*'**:
+
+```bash
+docker exec 004erpdb pg_dump \
+  -U $POSTGRES_USER \
+  -d $POSTGRES_DB \
+  --no-owner \
+  --no-acl \
+  --exclude-table-data='log_*' \
+  -Fc \
+  -f /tmp/prod_dump.dump
+```
+
+```bash
+docker exec 004erpdb sh -c 'pg_dump
+  -U "$TVOJ_USER"
+  -d "$TVOJA_BAZA"
+  --no-owner
+  --no-acl
+  --exclude-table-data='log_*'
+  -Fc
+  -f /tmp/prod_dump.dump'
+```
+
+---
+
+## Korak 2 — Kopiraj dump na lokalni PC
+
+Iz docker servera na host server:
+
+```bash
+docker cp 004erpdb:/tmp/prod_dump.dump /tmp/prod_dump.dump
+```
+
+```bash
+
+Iz lokalnog PowerShell terminala:
+
+```powershell
+scp tvoj_user@IP_SERVERA:/tmp/prod_dump.dump C:\Users\mario.tkalac\Downloads\prod_dump.dump
+```
+
+S SSH ključem:
+
+```powershell
+scp -i C:\Users\mario.tkalac\.ssh\id_rsa `
+  tvoj_user@IP_SERVERA:/tmp/prod_dump.dump `
+  C:\Users\mario.tkalac\Downloads\prod_dump.dump
+```
+
+Brisanje dump-a s produkcijskog servera (opcionalno):
+
+```powershell
+ssh tvoj_user@IP_SERVERA "rm /tmp/prod_dump.dump"
+```
+
+---
+
+## Korak 3 — Pokreni lokalnu bazu
+
+```powershell
+cd C:\Users\mario.tkalac\workspace\aplikacija\004.erp.generic
+
+docker compose -f docker-compose.yml up -d db
+```
+
+Pričekaj dok container postane `healthy`:
+
+```powershell
+docker ps --filter "name=004erpdb"
+```
+
+---
+
+## Korak 4 — Restoriraj dump u lokalnu bazu
+
+```powershell
+# Kopiraj dump file u container
+docker cp C:\Users\mario.tkalac\Downloads\prod_dump.dump 004erpdb:/tmp/prod_dump.dump
+
+# Dropaj lokalnu bazu i kreiraj novu praznu (BRIŠE lokalne podatke!)
+docker exec 004erpdb dropdb -U TVOJ_USER TVOJA_BAZA --if-exists
+docker exec 004erpdb createdb -U TVOJ_USER TVOJA_BAZA
+
+# Restoriraj
+docker exec 004erpdb sh -c 'pg_restore
+  -U "$TVOJ_USER"
+  -d "$TVOJA_BAZA"
+  --no-owner
+  --no-acl
+  -Fc
+  -f /tmp/prod_dump.dump'
+```
+
+> ⚠️ Zamijeni `TVOJ_USER` i `TVOJA_BAZA` s vrijednostima iz lokalnog `.env` fajla:  
+> `POSTGRES_USER` i `POSTGRES_DB`.
+
+---
+
+## Korak 5 — Primijeni nove migracije
+
+Pokrenuti odmah nakon restore-a kako bi lokalna shema bila u sinkronizaciji s kodom:
+
+```powershell
+docker compose -f docker-compose.yml -f docker-compose.dev.yml `
+  run --rm backend python manage.py migrate
+```
+
+Migracije na postojećim podacima su sigurne — dodaju tablice/stupce, ne brišu podatke.
+
+---
+
+## Korak 6 — Postavi lokalnog admin korisnika
+
+Produkcijske lozinke su hashirane i ne mogu se koristiti direktno. Kreiraj novog superusera:
+
+```powershell
+docker compose -f docker-compose.yml -f docker-compose.dev.yml `
+  run --rm backend python manage.py createsuperuser
+```
+
+Ili resetiraj lozinku postojećem accountu:
+
+```powershell
+docker compose -f docker-compose.yml -f docker-compose.dev.yml `
+  run --rm backend python manage.py changepassword tvoj@email.com
+```
+
+---
+
+## Korak 7 — Pokreni cijeli dev stack
+
+```powershell
+docker compose -f docker-compose.yml -f docker-compose.dev.yml up -d backend frontend
+```
+
+Provjeri:
+- Backend: `http://localhost:8001/api/`
+- Frontend: `http://localhost:4321/`
+
+---
+
+## Napomene o sigurnosti
+
+| Tema | Akcija |
+|------|--------|
+| **Produkcijska baza** | `pg_dump` je read-only operacija — produkcijska baza nije dirnuta |
+| **SECRET_KEY** | Lokalni `.env` **mora** imati drugačiji `SECRET_KEY` od produkcije |
+| **DEBUG** | Lokalni `.env` mora imati `DEBUG=True` |
+| **Media fajlovi** | Dump ne uključuje fajlove iz `media_volume`; kopirati ručno ako su potrebni |
+| **Osobni podaci** | Baza može sadržavati osobne podatke klijenata — koristiti samo na zaštićenom lokalnom stroju |
+
+---
+
+## Media fajlovi (opcionalno)
+
+Ako trebaju priloženi fajlovi (slike, PDF-ovi):
+
+```bash
+# Na produkcijskom serveru — arhiviraj media
+docker run --rm \
+  -v media_volume:/data \
+  alpine tar czf /tmp/media.tar.gz -C /data .
+
+# Kopiraj lokalno
+scp tvoj_user@IP_SERVERA:/tmp/media.tar.gz C:\Users\mario.tkalac\Downloads\media.tar.gz
+```
+
+Raspakiraj u lokalni Docker volume:
+
+```powershell
+# Kopiraj arhivu u privremeni container
+docker run --rm `
+  -v 004erpgeneric_media_volume:/data `
+  -v C:\Users\mario.tkalac\Downloads:/backup `
+  alpine sh -c "tar xzf /backup/media.tar.gz -C /data"
+```
+
+---
+
+## Brzi pregled naredbi (cheat sheet)
+
+```bash
+# 1. Dump na serveru
+docker exec 004erpdb pg_dump -U USER DB --no-owner --no-acl -Fc -f /tmp/prod_dump.dump
+
+# 2. Kopiraj lokalno
+scp user@IP:/tmp/prod_dump.dump ~/Downloads/prod_dump.dump
+
+# 3. Restore lokalno
+docker cp ~/Downloads/prod_dump.dump 004erpdb:/tmp/prod_dump.dump
+docker exec 004erpdb dropdb -U USER DB --if-exists
+docker exec 004erpdb createdb -U USER DB
+docker exec 004erpdb pg_restore -U USER -d DB --no-owner --no-acl -Fc /tmp/prod_dump.dump
+
+# 4. Migracije
+docker compose -f docker-compose.yml -f docker-compose.dev.yml run --rm backend python manage.py migrate
