Completes the services/ TypeScript migration (0 .js remain). These four are the
largest, most dynamic modules (subscription-catalog matcher, xlsx/spreadsheet
parser, OIDC protocol client, SQLite user-DB importer); converted to .cts with a
top-of-file @ts-nocheck so they run via Node type-stripping now, with rich typing
deferred as an incremental follow-up. The other ~46 services are fully typed.
Behavior-preserving. Verified: typecheck:server 0, check:server 0, suite 226/226.

Two of the large foundational services. billsService (validation/normalization,
balance math) is required by many others; notificationService (email + push +
drift digest) uses the shared http types indirectly.

Establishes the server-TypeScript foundation and migrates utils/money →
utils/money.mts with branded Cents/Dollars (mirroring the client), so the
cents↔dollars boundary — the origin of the reconciliation bug class — is a
compile error for any typed server caller.
Approach (no build step): Node 25 runs .ts natively (type-stripping).
Migrated modules use the explicit-ESM .mts extension (the project is
"type":"commonjs", which disables .ts ESM auto-detection) and are required
from the CJS callers via Node's require(esm) — verified working. Infra:
tsconfig.server.json (allowJs + checkJs:false → incremental like the
client), npm run typecheck:server, check:server extended to .mts, wired
into ci. 28 require sites repointed to money.mts.
typecheck:server clean; full server suite 225 + e2e probe 17/17 green.

- Rewrite detectAllHeaderSets() with repeat-field detection instead of gap-based splitting
- Require ≥2 header fields per group (filters out false matches like 'Left Over | Paid')
- Fix column leakage: right-side bills no longer pick up left-side amounts
- Add header_set_index to analyzeRow return object for frontend use
- Add isLikelySummaryRow() filter (Paycheck, Left Over, Enter how much, etc.)
- Expand isLikelyTotalRow() to catch 'Auto Total ------>' patterns
- Filter leftover calc rows (null name + negative amount, dash separators)
- Remove 'paid' from HEADER_PATTERNS.amount (was false-matching 'Paid' cells)
- Skip empty string cells in detectAllHeaderSets
- detectAllHeaderSets() finds multiple header groups per row (left 1st / right 15th)
- isBlankRowForHeaderSet() checks blanks per column range for dual layouts
- parseSheetRows() scans rows 0-4 for header row, processes each set independently
- analyzeRow() computes due_day from date/label/pattern with fallback to defaultDueDay
- Cell type validation allows 's' (shared formula) type
- Non-numeric amounts (auto, double pay, past due) become detected labels
- Day patterns (1st, 15th, 24th) parsed as due_day values
- Security: bounds validation in isBlankRowForHeaderSet, anchored regex, label sanitization
