Fix unused imports, restore email provider API backward compat, add authBehavior/email config tests

[Copilot]

Three issues flagged in PR review on the config migration and package toggles work.

Unused imports — createAppConfig.ts

AuthBehaviorConfig and EmailConfig were imported but never referenced, breaking @typescript-eslint/no-unused-vars.

// Before
import { AppConfig, AppMeta, AuthBehaviorConfig, ConfigOptions, EmailConfig, ... } from './types';

// After
import { AppConfig, AppMeta, ConfigOptions, ... } from './types';

Breaking API change — email.ts

handleEmailProviders() dropped the optional field and replaced it with configNote, breaking clients reading provider metadata. Both fields now coexist.

// After: backward-compatible shape
resend: {
    available: !!env.EMAIL_RESEND_API_KEY,
    required: ['EMAIL_RESEND_API_KEY'],
    optional: ['EMAIL_FROM'],                          // restored
    configNote: 'Sender address configured in ottabase.config.ts → email.from',  // new
},

Missing tests — config.test.ts

Added coverage for the new email and features.authBehavior config sections introduced in the base PR:

• Default values for email.from, email.sesRegion, and all four authBehavior flags
• Env var override behavior for EMAIL_FROM, AWS_REGION, AUTH_SESSION_MAX_AGE, AUTH_REQUIRE_EMAIL_VERIFIED, AUTH_DISABLE_CREDENTIALS, AUTH_VERBOSE

Pull request overview

This PR addresses follow-up issues from the config migration/package toggles work by fixing a lint-breaking unused import, restoring backward compatibility in the email provider metadata API, and adding tests for newly introduced config sections.

Changes:

• Remove unused type imports in createAppConfig.ts to satisfy @typescript-eslint/no-unused-vars.
• Restore optional metadata fields in /api/email/providers response while keeping the new configNote.
• Add unit tests for email and features.authBehavior defaults and env var overrides.

• The outer describe('Configuration Utilities', ...) block is not closed at end-of-file after adding these new test suites. This leaves the file with unbalanced braces/parentheses and will cause the test file to fail to parse/compile. Add the missing closing }); at the end.

These tests mutate process.env and then delete the keys in finally. If the env var was already set in the test runner/CI, this will wipe the original value and can make other tests flaky. Save the previous value before overriding and restore it in finally (set it back if it existed, otherwise delete).

Same process.env cleanup issue here: deleting the env vars in finally can remove values that were already set before the test ran. Prefer restoring the previous values to avoid leaking state across tests.
