feat(ingest): improve sync schedule UX with toggle, info tooltip, and conditional fields

[rajatoss]

Summary

Improves the ingestion Sync Schedule UX so a disabled schedule no longer shows confusing time controls, and the "Run on a schedule" affordance reads more clearly.

Applies to both schedule builders:

• ScheduleSection.tsx — the new multi-step builder (shown when the ingestionOnboardingRedesignV1 flag is on)
• CreateScheduleStep.tsx — the legacy modal builder (shown when the flag is off)

Changes

• Inline toggle — the enable/disable switch now sits directly next to the "Run on a schedule (recommended)" heading instead of below it.
• Info tooltip — the copy "Keep metadata current by automatically syncing on a regular interval" moved out of the toggle label into a hover tooltip on an ⓘ icon, decluttering the row.
• Conditional fields — the cron schedule (Every / at / time / View Advanced Settings) and the timezone selector now render only when the toggle is enabled. When disabled, the user just sees the toggle plus the existing out-of-date warning.

Checklist

• PR conforms to the Contributing Guideline (PR Title Format)
• Tests added/updated (if applicable) — N/A, presentational change
• Docs added/updated (if applicable) — N/A
• No breaking changes
