 * Filters service status incidents based on related tickers or Ledger components.
 *
 * ## Behavior:
 * - If there are no `tickers` or no `incidents`, returns an empty list.
 * - For each incident:
 *   1. ✅ If the incident has no components → keep it (always relevant).
 *   2. ✅ If at least one component name matches a known **Ledger component** → keep it.
 *   3. ✅ If at least one component name contains a **currency ticker** → keep it.
 *   4. ❌ Otherwise, the incident is discarded.
 *
 * @param {Incident[]} [incidents=[]] - List of incidents to filter.
 * @param {string[]} [tickers=[]] - List of currency tickers to match against incident components.
 * @param {EntryPoint} [entryPoint] - Entry point where the incidents are displayed (specifically for Ledger components)
 * @returns {Incident[]} The list of incidents relevant to the provided tickers or Ledger components.
