* Fixes#11856
* Set the minimum recommended wordlist size to 1,296 - equal to the EFF Short List
* Issue a clear warning when using a smaller wordlist but do not prevent generation of passphrases
* Improve wording when removing custom wordlist
* An additional approach to create passphrases with one random word being in UPPERCASE.
* Also remove duplicate character count from passphrase generator

Replace a QVector for the wordlist with a QSet. This removes all duplicate entries in a given wordlist.
Thus, it hinders a malicious wordlist that has the proper length (>4000 entries) but with repetitions (effectively << 4000 entries) to be used and potentially create weaker passphrases than estimated.
Example:
List with 4000 items but only 64 unique words would lead to only 48 bit of Entropy instead of ~95 bit!
* Pass correct entropy amount to keepassxc-browser instead of amount of bits for both password and passphrase.
* Rename json key from "login" to "entropy" (keeping "login" key for backwards compatibility).
* Also make some changes to entropy calculation methods:
- Rename PassphraseGenerator::calculateEntropy to estimateEntropy
- Rename PasswordGenerator::calculateEntropy to estimateEntropy
