Curation flags update

[daniaki]

• Rename the second ‘STR/Low complexity’ flag (under ‘dubious read alignment’) to ‘Repetitive sequence’. This is to avoid confusion with the other similarly named flag under ‘Mapping errors’.
• Add ‘Minor protein isoform (MANE/APPRIS)’ flag to the ‘Inconsequential transcript’ section. If possible, could this be placed after ‘Minority of transcripts ≤ 50%’ flag in the list?
• Add ‘Sanger confirmation recommended’ as a flag to the ‘Comments’ section.
