Fix Hive reauth loop by persisting device metadata; add debug 2FA toggle

[tamunro93]

This PR addresses a reauth loop seen when Hive refresh token fallback occurs after an initially successful login.

In affected cases, login returns AuthenticationResult with NewDeviceMetadata, but device_data is not persisted in the config entry. Later fallback device auth then fails and repeatedly reauths.

This PR:

• persists/registers device metadata immediately when login succeeds with NewDeviceMetadata
• adds an optional Disable 2FA (debug) toggle in config flow for troubleshooting
• adds sanitized auth payload logging (tokens/secrets masked)
• updates dependency to pyhive-integration==1.0.8.dev10 (as currently tested)

Changes

• config_flow.py
• replaces passthrough flow with local flow implementation
• on successful login, if AuthenticationResult.NewDeviceMetadata exists:
• sets auth access/device fields
• performs device_registration
• persists self.data["device_data"] = await self.hive_auth.get_device_data()
• adds optional debug toggle for bypassing MFA submission during diagnostics
• adds sanitized debug/warn logging for auth payloads
• const.py
• adds CONF_DISABLE_2FA_DEBUG
• strings.json
• en.json
• adds UI/error text for debug toggle path
• manifest.json
• pyhive-integration -> 1.0.8.dev10

Repro / Symptoms
Observed recurring errors before fix:

• Refresh token is invalid or expired
• Device login failed: expected DEVICE_SRP_AUTH challenge, got None
• Config entry ... could not authenticate
• Result

After this patch, device_data is persisted for successful login flows returning NewDeviceMetadata, and the reauth loop is resolved in my tested environment.

Notes:

I understand 1.0.8.dev10 is a dev dependency and may change before official 1.0.8. Happy to adjust dependency/version strategy based on maintainer preference. Also, thanks for the heads-up on the other 1.0.8 dev PR; happy to align/rebase this against it or reduce this PR to only the debug-toggle bits if preferred.
