fix(reader): correct import paths after directory restructuring

Update import statements to reflect new module locations:
- panel-editor.ts: fix Alpine and api imports
- copy-handler.ts: fix ReaderContext and toast imports

These corrections address path issues caused by the reader
architecture refactor where modules were moved into
format-specific subdirectories.
