Bugfixes: Reports and inventory issues fixed

Reports:

An error in the portfolio report was fixed that occurred when the Portuguese language is selected.

We fixed a bug where on big roadmap reports, the alignment of dependencies would be rendered multiple lines lower than actually required. This has been solved now.

Inventory:

We reduced the minimum screen size of the Inventory's dialog for creating new Fact Sheets, so users can adequately utilize the 'Create' button for creating Fact Sheets with categories.

The Excel import now performs validation of the formatting of email addresses for subscriptions. An exception in the resulting spreadsheet informs about possible non-conformance to RFC 5322 syntax for email addresses.
