/**
 * alertRules.tickers — watchlist ticker-scope persistence + normalization
 * tests (#4922 item e / U3). Server-side mirror of the U12 `countries`
 * field (see alertRules-countries.test.ts, the behavioural model).
 *
 * Covers:
 *  - normalize-on-write: trim, uppercase, regex filter, dedupe
 *  - shape: `^[A-Z][A-Z0-9&-]{0,11}(\.[A-Z]{1,3})?$` — plain symbols
 *    (AAPL), share-class/conglomerate forms (BRK-B, M&M.NS) and
 *    dot-suffixed listings incl. long NSE bases (RELIANCE.NS,
 *    BHARTIARTL.NS) pass; cashtag junk ($AAPL), carets (^GSPC),
 *    futures (GC=F) are silently dropped
 *  - cap at TICKERS_MAX (50) — throws on overflow
 *  - backward compat: omitted on insert → field absent on row
 *  - preserve-on-omit: caller omits `tickers` → existing value retained
 *  - explicit reset: caller passes [] → row stores []
 *  - internal mutations (setAlertRulesForUser, setNotificationConfigForUser)
 *    forward + normalize tickers — these are the API/http passthrough targets
