Batch send templates and address-book integration

[truthixify]

Tier: S (1-2 days) | Type: feature

Context. src/pages/StellarSplit.tsx accepts a CSV paste per session. Payroll-style users run the same list every cycle and want templates. Contacts from the address book should also autocomplete each row.

Scope.

• Save-as-template control on the Split page, listing saved templates on load.
• Per-row combobox that suggests entries from contactsStore.
• Rename / delete / duplicate template actions.
• Export / import templates as JSON (round-trippable with existing address-book export).

Acceptance.

• Load-template restores the exact row set and amounts
• Combobox uses the ARIA pattern already established in address-book send autocomplete
• Export -> import round-trip test
• Templates survive reload

Files. src/pages/StellarSplit.tsx, src/store/splitTemplatesStore.tsx (new), src/store/contactsStore.tsx.

I’ll start by checking how StellarSplit currently handles CSV rows and how contactsStore handles autocomplete. Then I’ll add template saving and loading with persistent storage, plus rename, duplicate, delete, import, and export support.

I’ll also make sure the existing ARIA autocomplete pattern is reused and add tests for restoring rows exactly, JSON round trips, and templates surviving reloads.
