fix(storage): parse enums properly

[Caceresenzo]

Fix incorrect parsing of the OTP algorithm introduced in version 8.0.0 to enable this feature.

The code before (in v7.0.0):

Authenticator/src/models/storage.ts

Lines 383 to 384 in bf630cc

	data[hash].algorithm =
	data[hash].algorithm || OTPAlgorithm[OTPAlgorithm.SHA1];

The code after (in v8.0.0):

Authenticator/src/models/storage.ts

Lines 490 to 492 in 2cf9b0f

	algorithm: rawAlgorithm
	? (parseInt(rawAlgorithm) as OTPAlgorithm)
	: OTPAlgorithm.SHA1,

@mymindstorm parsed the algorithm-friendly name (SHA***) as an integer instead of casting the enum directly. This resulted in a NaN, which would be stripped during serialization.

Since SHA1 is now considered insecure, companies are likely using SHA256, which cannot be parsed and defaults to SHA1.

I wasn't sure if keeping undefined was what you wanted. Revert 1fc616b if you think it's better to always use SHA1 as the default.

It's the same parsing mistake for the type, but this one "worked" because the fallback was OTPType.totp (the most commonly used).
