Feat/Complete Sales Summaries (#5)

## Summary

Completes the automatic sales summary pipeline end-to-end: the `sales-summaries-v2` job now calculates aggregate totals, preserves manual adjustments, and automatically posts balanced journal entries to the ledger.

## What Changed

**New Datomic transaction function** (`upsert-sales-summary-ledger`)
- Transforms detailed `sales-summary-item`s into aggregated `journal-entry` lines grouped by account and ledger side
- Handles the full upsert: posts a new journal entry for summaries with mapped accounts, or retracts the orphaned entry if items no longer qualify

**Enhanced `sales-summaries-v2` job**
- Calculates and stores 13 aggregate total attributes (card/cash/food-app/gift-card payments, refunds, fees, discounts, tax, tip, returns, unknown, net)
- Preserves manual items (`manual? true`) during recalculation — only auto-calculated items are replaced

**Ledger reconciliation**
- `reconcile-ledger` now queries for sales summaries missing journal entries and repairs them via `:upsert-sales-summary-ledger`, alongside existing invoice and transaction repairs

**Schema**
- Added 13 `total-*` attributes on `sales-summary` (all `db.type/double`, no history)
- Registered the new transaction function in `tx.clj` and `datomic.clj`

**Admin UI cleanup**
- Resolved "clientize" and HTMX `client-id` TODOs in the sales summaries admin page
- `new-summary-item` now correctly passes `client-id` via `hx-vals`
- Removed stale TODO comments and placeholder code
