[NGS Portal] Pipeline run's report documents

**Background**

During pipeline execution, many different auxiliary output documents may be generated.
Once pipeline is completed, user might want to view/preview such documents or download them to work with later.
As these documents can be located in different places of the pipeline working/output directory and it can be hard to find files of interest manually, it would be useful to implement a separate previewer for pipeline output documents.

**Approach**

On the Run logs page of the pipeline, a new tab shall be added - **Reports**.
This tab shall have a view like:


Tab shall contain a list of documents from the pipeline's output directory:
- list shall include only documents loaded via `PipelineResult` storage rules (for more details see #3906)
- documents shall be grouped by storage rules by which they were loaded

List shall have a table view with the following columns:
- _Name_ - name of the `PipelineResult` storage rule by which documents were loaded
- _Path_ - list of full paths of documents loaded via the corresponding `PipelineResult` storage rule
- each path shall be presented as hyperlink - by click it, a corresponding document shall be opened in a preview pop-up (see below)
- if the list of documents is too large (more then `N` documents for a rule, where `N` is defined from preferences) then only several documents shall be shown, other documents shall hidden and a control with the count of hidden paths shall be shown. By click such control, list of hidden document shall be shown in a tooltip, e.g.:

Table shall support sorting by the _Name_ column.

By click any document path, the pop-up with document preview shall be opened.
This pop-up shall look like:


Pop-up shall include:
- details section:
- labels with the document name (name of the `PipelineResult` storage rule by which that document was loaded) and path
- button to open current document in a new tab
- button to download a raw file of the current document to the user workstation
- preview section - main section with the document preview. At least the following types and viewer shall be supported:
- `TSV`, `CSV` - shall be shown as a formatted table. Sorting by columns shall be supported. Pagination shall be supported for large tables
- `PDF` - shall be shown in a web PDF-viewer inside a frame
- `PNG` - shall be shown as image inside a frame
- `HTML` - shall be shown as formatted HTML-page inside a frame
- for unsupported documents types:
- notification shall be shown about the impossibility of previewing and a suggestion to download the document
- button to open a document in a new tab shall be disabled

Start at the pipeline Run logs page and trace how PipelineResult storage rules expose output files; review issue #3906 and the preferences controlling path limits. Done means a Reports tab groups and sorts eligible documents, supports path limits and previews for the listed formats, and provides the specified download and open actions.
