feat: SDK update for version 27.1.0

[ChiragAgg5k]

This PR contains updates to the SDK for version 27.1.0.

What's Changed

• Added: account passkey methods listPasskeys, createPasskey, getPasskey, updatePasskey, deletePasskey and updatePasskeyVerification
• Added: account.createPasskeyToken and account.updatePasskeyToken for passkey sign-in
• Added: Passkey, PasskeyList, PasskeyChallenge and TokenSecret models

Passkeys only, patched onto 27.0.0: the diff of the SDK generated with and without the passkey methods, three-way merged onto the release. Everything else on the release is unchanged, including its X-Appwrite-Response-Format.

The new API methods, models, exports, and version metadata are consistent with the surrounding SDK patterns, and I found no concrete behavior issue in the reviewed changes.

Adds Flutter SDK 27.1.0 support for passkey registration, management, and sign-in, along with the corresponding response models and examples. Updates package and client SDK version metadata while preserving the response-format header.
