[PERF] l10n_cl_edi,l10n_cl_edi_stock: speed up attachment deletion

Enterprise18.0l10n_cl_edil10n_cl_edi_stockMEDIUM

Attachment deletion is now much faster for Chilean electronic invoicing and stock documents. This reduces delays in databases with large numbers of invoices or deliveries, improving day-to-day performance without changing business workflows.

Original PR description

## The problem

Deleting attachments checks foreign key triggers. Lookups in `account_move` and `stock_picking` tables for `ir_attachment` related fields coming from `l10n_cl_edi` overrides were slow due to missing indexes.

## The solution

Added needed indexes to optimize triggers' lookups.

## Benchmark

Time benchmark (deleting attachments from a customer database with 224K account moves and 204K stock pickings):
|# of rows|Time (Before)|Time (After)|
|----------|--------------|-------------|
100 | 29s | 16ms
1000 | 285s | 300ms
