feat: filemanager API wildcards

[mmalenic]

Closes #456

Changes

• Add wildcard matching to API routes for list/update.
  • Wildcards use '%' for multiple characters and '_' for single characters, which get converted to like queries.
  • case_sensitive can be used to control whether the query is like or ilike.
  • Wildcards are also supported in JSON attributes.
• Add API guide and design docs.
• Update tests and OpenAPI definitions.
