Custom schema eln issues

• no validation for uploaded schemas: esp. missing sub_section in SubSection (aliases are not working here)
• system attempts to use schemas with failed processing
• ReferenceEditQuantity used qualified names like *.Sample to search for entries with respective section, metadata.sections are stored with qualified names and not with full references.
• The selection of entry types does not update after processing
• The selection of entry types does only show a simple name (with e.g. a package name)
• custom schema packages with names do not work, because they are interpreted as python names by the processing
• abstract sub-sections do not have a selection
• autoselection of eln edit components
• delete and re-upload button on entry overview
• entries with custom schema (e.g. only definitions) do not get a entry_name
• search for quantities in data does not work, because the view is not showing sub-classes (let alone sub-classes comming from custom schemas).
• the browser does not show quantities/sub-sections from the custom schema elements (but they are in the data?)
• basic ELN search
• metainfo browser does not show sub classes of sub sections
• tables parsing with "smart" column mapping
• excel upload
• better section preview cards
• all "eln results" show on the metadata left side view
• cross upload references
• chemical (and sample) normalize into results.material
• yaml direct sub section defs
• metainfo browser does not support multiple base-sections
• navigation for referenced sections
• navigation from the tree file browser
• table card with some overview?
• refresh button on upload page (and entry page?)
• metainfo browser shows annotations
• entry files tab opens the actual mainfile
