Changed member welcome email job to run based on config

Benchmark PR from qodo-benchmark#246

Bug: The condition if (hasScheduled.processOutbox && ...) will never execute because hasScheduled.processOutbox is initialized to false and only set to true inside the unreachable block.
_{Severity: HIGH}

Suggested Fix

The condition should be inverted to check if the job has not been scheduled yet. Change if (hasScheduled.processOutbox && !process.env.NODE_ENV.startsWith('test')) to if (!hasScheduled.processOutbox && !process.env.NODE_ENV.startsWith('test')).

Potential issue: The `scheduleMemberWelcomeEmailJob` function contains a logical
deadlock. The `hasScheduled.processOutbox` flag is initialized to `false`. The condition
to schedule the job checks `if (hasScheduled.processOutbox && ...)`, which will always
evaluate to false on the first run. The line that would set `hasScheduled.processOutbox
= true` is inside this unreachable conditional block. As a result, the
`process-member-welcome-emails` job will never be scheduled, and member welcome emails
will never be sent.

Bug: The condition welcomeEmailConfig || WELCOME_EMAIL_SOURCES.includes(source) should use && instead of ||. The current logic sends welcome emails when it shouldn't, such as for imported members.
_{Severity: MEDIUM}

Suggested Fix

The logical OR || operator should be replaced with a logical AND && operator. The condition should be welcomeEmailConfig && WELCOME_EMAIL_SOURCES.includes(source) to ensure an outbox entry is created only when both the feature is configured and the member creation source is valid.

Location:
ghost/core/core/server/services/members/members-api/repositories/MemberRepository.js#L342

Potential issue: A logical condition was changed from `&&` to `||`, causing incorrect
behavior for creating member welcome email outbox entries. The new condition
`welcomeEmailConfig || WELCOME_EMAIL_SOURCES.includes(source)` creates an entry if
either the config is set OR the source is 'member'. This means emails will be sent for
all sources (e.g., 'import') when the config is enabled, and will also be sent when the
config is disabled if the source is 'member'. Both behaviors are incorrect and break
existing tests.
