[CLI] list --detail: count entries without decryption

[moonD4rk]

Current Behavior

list --detail calls Extract() for each browser, which performs full extraction: copying files to temp directory, retrieving the master key, decrypting all data — only to count the number of entries per category.

Problem

• Decryption is unnecessary just to count entries
• Wastes resources (file copy, key retrieval, decryption)
• When master key is unavailable, encrypted categories (password, cookie, creditcard) show count as 0, which is misleading — the data exists, it just can't be decrypted

Expected Behavior

Count entries directly from the database (SELECT COUNT(*)) without decryption. No master key needed, no temp file copying, much faster.
