feat(core,fuse,gui): rebuild Trash and shared pages on one file list

The list and grid view from My files moves into widgets/file_list.rs as
FileList, so Trash, Shared with me and Shared by me share its columns,
selection, context menus, keyboard handling and list/grid switch instead of
each drawing its own rows.

Trash shows where each item came from and when it was deleted. Proton does
not expose the trash time through the SDK yet, so the daemon records when it
first sees a node in the trash (migration V35, trash_seen) and reports that;
the date becomes exact once proton-sdk-rs exposes Node::trash_time. Restoring
offers a Show action, and opening a trashed item explains that it needs to be
restored first.

Shared with me splits files and saved links into two views. Files show who
shared them, with a warning pill for unverified senders, the access they give
and when they were shared. Pending invitations sit in a banner that opens a
dialog to accept or decline each one. Several items can be left at once.
Saved links get their own list with open, copy and remove actions.

Shared by me gains a filter (all, links, people, expired links) and columns
for location, people and link state, with a copy button for live links.
Several items can stop being shared at once, the page refreshes after the
share dialog closes, and a reload rebinds only the rows that changed so the
selection survives.

All catalogs are updated and complete.
