feat(dimentorin): implementasi avatar inisial mentor + resume dinamis + fix dummy data

- Komponen baru MentorAvatar: gradient unik per nama (hash), inisial nama, reusable (sm/md/lg + textClassName)
- Kartu mentor: ganti img testimonial.webp statis -> avatar inisial gradient (MU, dll)
- Detail mentor profile: avatar besar + fix hardcoded tanggal 'Jum, 4 April 2025' -> tanggal dinamis id-ID
- Senpai Resume: fallback dinamis dari data mentor (role/experience/expertise/industries/languages) saat bio kosong, bukan 'Belum ada deskripsi'
- Booking modal topic step: ganti nama mentor hardcoded 'Muhammad Firdaus Oi Oi Oi' -> dari prop mentor + avatar
- Booking modal payment step: avatar mentor di summary
