fix(Material Requirements Planning Report): detailed-view chart timescale

The detailed-view chart collapsed every row into a single "today" column
and was additionally capped at 10 points, so the chart never matched the
report's date filters or the table data.

Two causes in get_detailed_view_chart_data:

1. `row.deliver_date` was a typo for `row.delivery_date` (the name used
   everywhere else in this report). On a frappe._dict the missing
   attribute resolves to None, so `getdate(None)` returned today and the
   past-date filter silently compared every row against today instead of
   its own delivery date.

2. A hard `if i == 10: break` truncated the chart to 10 date buckets.

Use the correct field name and drop the cap. The null check now runs
before the date comparison, since `getdate(None)` returning today meant
the original ordering could never filter a null delivery_date out.

Fixes #52632
