feat(branch): tambah kolom baru dan dukungan pencarian terkait data cabang

- Menambahkan kolom baru pada tabel `branches` melalui migrasi:
  - `address`
  - `mnemonic`
  - `customer_company`
  - `customer_mnemonic`
  - `company_group`
  - `curr_no`
  - `co_code`
  - `l_vendor_atm`
  - `l_vendor_cpc`
- Memperbarui model `Branch` agar mendukung kolom baru di properti `fillable`.
- Menambahkan dukungan pencarian berdasarkan kolom `address` pada:
  - `BranchExport.php` (untuk ekspor data)
  - `BranchController.php` (untuk API pencarian data cabang)
- Memperbarui tampilan daftar cabang (`branch/index.blade.php`) untuk menampilkan kolom `address`.
- Memperbarui format data ekspor cabang dengan menambahkan kolom `address`.
- Memperbaiki pengaturan format kolom tanggal pada data ekspor.
