Add open text fields for Manufacturer and Software Product Name in GEAR Manager

Adding open text fields is a workaround due to our tech catalog subscription ending. It gives the CTO team the ability to add the names manually if they do not appear in the tech catalog data, since that data will grow staler over time. We must ensure that the CTO team knows about this and is reliably being consistent with their naming conventions so that we don't have multiple entries for the same Manufacturer.

In our meeting, we discussed adding 2 tables in gear_schema, one for manufacturer and one for software product name. This will be a searchable field in GEAR Manager that will also pull from the tech_catalog schema for both the manufacturer name and software product name.

Make hybrid fields (i.e. the ability to choose from dropdown or add custom value) for Manufacturer, Product, and Software Version. If fields are manually entered, make Software Release field a concatenation of Manufacturer + Product + Software Version.

Remove Vendor End of Life Date for now. We can bring this back if we get our tech catalog subscription back.
