Fix label printing when using countAmt repeat fields

[AChaourova]

Fixes #3434

Description

Restores Specify 6 style label repetition behaviour when printing labels.

This change adds support for:

• Spreport.RepeatField repeating rows based on a field value (for example countAmt)
• Spreport.RepeatCount repeating rows a fixed number of times
• JRXML-based repetition using the specify.repeat.count.field property

The backend now expands report rows before sending data to the report renderer, and the report ID is passed from the UI to the report runner so stored report repetition settings can be applied.

Automated tests have been added for repeat-field expansion, repeat-count expansion, precedence rules, JRXML fallback behaviour, and end-to-end report execution.

This change restores Specify 6 label repetition behaviour using
RepeatField, RepeatCount, and the
specify.repeat.count.field JRXML property.
No database schema changes or migrations are included in this PR.

Testing instructions

1. Open a label/report that has RepeatField configured to use countAmt.
2. Run the label against records where countAmt has different values.
3. Verify labels are generated according to the countAmt value.

• countAmt = 3 produces 3 labels
• countAmt = 2 produces 2 labels

4. Verify null, zero, or invalid values default to a single label.
5. Verify labels using RepeatCount still repeat the configured number of times.
6. Verify labels without repetition settings continue to behave as before.
7. Run the automated report runner tests.

Summary by CodeRabbit

• New Features

  • Reports can repeat result rows based on a configured field value, fixed repeat count, or report setting.
  • Report identification is preserved when launching reports from record and record-set views.

• Bug Fixes

  • Improved report execution so repeated labels and rows follow configured repetition settings.
  • Invalid, missing, zero, or non-numeric repeat values safely produce a single row.
  • Repeat settings are ignored when the submitted report does not match the selected query or record context.

📝 Walkthrough

Walkthrough

The report UI submits an optional report ID. The backend validates its association with the query and scope before applying repetition settings. Tests cover field-based repetition, fixed counts, precedence, JRXML fallback, and invalid values.

Changes

Report row repetition

Layer / File(s)	Summary
Report ID propagation specifyweb/frontend/js_src/lib/components/Reports/Report.tsx, ForRecord.tsx, RecordSets.tsx, Parameters.tsx, Run.tsx	Report components pass the optional report ID to RunReport, which renders it as a hidden form input when defined.
Validated row expansion specifyweb/backend/report_runner/views.py	The runner validates the report ID against the query, discipline, collection scope, and user. It then applies RepeatField, RepeatCount, or the JRXML repeat-count property in precedence order.
Row expansion validation specifyweb/backend/report_runner/tests.py	Tests validate helper behavior, configuration precedence, JRXML fallback, invalid values, matching report settings, and ignored settings from mismatched reports.

Full details: Testing Instructions

Explanation

The instructions clearly cover RepeatField, RepeatCount, per-row counts, invalid values, and reports without repetition settings. They do not explicitly test the changed JRXML specify.repeat.count.field behavior. They also do not state the expected result when reportId does not match the submitted query, collection, or user. The pull request adds both behaviors in views.py and adds an end-to-end mismatch test. The final instruction to run the report runner tests is too broad to communicate these required checks.

Resolution

Add a JRXML test step. Configure specify.repeat.count.field to the countAmt result field, run the label, and verify that rows repeat by that value when no stored RepeatField or RepeatCount applies. Add a report-ID validation step. Run a report with its valid reportId and verify stored repetition settings apply, then submit a different query or collection with the same reportId and verify the stored settings are ignored. State the exact command or test target for the automated report runner tests.

configured maximum cumulative expanded-row count before any list multiplication
or allocation, rejecting the report when the limit would be exceeded. Preserve
valid expansion behavior at or below the boundary, and add boundary tests
covering both helpers.
- Line 124: Update the repeat-count precedence check around
_expand_rows_by_count() to test report.repeatcount is not None, so persisted
zero is treated as configured and takes precedence over the JRXML repeat field.
Add a test covering repeatcount=0 alongside a JRXML repeat value.
- Around line 159-164: Validate request.POST.get('reportId') against the
submitted report/JRXML query association before calling _expand_rows_for_repeat;
if the ID is missing or does not belong to that report, do not apply its stored
repeat settings. Preserve repeat expansion only for a valid associated report
ID.
