Sort office search newest-first and cap at 500 results

[juliusknorr]

Adds <d:orderby> (getlastmodified descending) and <d:limit> (500) to the WebDAV SEARCH so the server returns only the 500 most recently modified office files. UI display cap raised to match.

@juliusknorr I'm not so familiar with the server, but does this not mean the frontend will not be aware of other files and therefore can't show a button to load more?

office/src/views/OfficeOverview.vue

Line 120 in adabbb1

const hasMoreFiles = computed(() => filteredFiles.value.length > MAX_DISPLAY_FILES)

@juliusknorr Is there some meta endpoint we can ping to get file count?

[moodyjmz]

I asked Claude: No — Nextcloud's DAVSEARCH doesn't support RFC 5323 aggregate COUNT, and there's no OCS endpoint for a mime-type file count either. The only way to know the true total is to fetch all
matching files, which is exactly what this PR avoids doing.

The practical fix for hasMoreFiles is simpler: if the server returned exactly 500 results, assume there may be more and show a "showing newest 500" notice rather than trying to compute
an exact count.

A fix

Current (src/views/OfficeOverview.vue:119–120):

  const files = computed(() => filteredFiles.value.slice(0, MAX_DISPLAY_FILES))
  const hasMoreFiles = computed(() => filteredFiles.value.length > MAX_DISPLAY_FILES)

Fix:

  const files = computed(() => filteredFiles.value)
  const hasMoreFiles = computed(() => allFiles.value.length >= MAX_DISPLAY_FILES)

Ok, let me adjust, then we need to also pass the offset to the search request.
