Fix: consolidate and extend unicode NFC normalization for filenames and matching

Consolidates the scattered unicodedata.normalize("NFC", ...) calls introduced
by my earlier filename/path normalization work into a single
documents.utils.normalize_unicode() helper, and closes several gaps where
NFD-normalized filenames could still slip through unnormalized:

- Document.get_public_filename() now normalizes, fixing exported filenames
  built from an NFD title/correspondent name (the default, non-format export
  path was not covered by the earlier fix).
- DocumentViewSet.update_version() now normalizes the uploaded filename,
  matching PostDocumentView's existing behavior.
- ConsumerPlugin normalizes self.filename once at consumption time, covering
  the title fallback and Document.original_filename for every document
  source (consume folder, mail, API, barcode splits).
- Workflow trigger and mail rule filename/path matching (documents/matching.py,
  paperless_mail/mail.py) now normalize the document/attachment side before
  comparing, so an NFD filename matches an NFC-typed filter pattern instead of
  silently failing to match.
- WorkflowTriggerSerializer and MailRuleSerializer normalize filter_filename/
  filter_path and the attachment include/exclude patterns once at write time,
  so the read side isn't re-normalizing an already-canonical value on every
  match.

-- `checksum` matches the checksum of the original document file (not the archived/processed version). Unlike the text fields, this one is stored verbatim rather than tokenized, so only a complete, lowercase checksum matches. To search by the first few characters instead, use a wildcard: `checksum:9f86d081*`. Wildcard patterns on the text fields are also tried stemmed, to line up with the stemmed index, but `checksum` is indexed without stemming, so its patterns are not stemmed either: a wildcard prefix is matched literally, apart from being lowercased first. `checksum:9F86D081*` therefore does find the document, even though the plain uppercase term does not.

 Matching inexact words:
 
 ```

 ```
 
-Wildcards are matched against the _stemmed_ terms stored in the index, not
-against the words as they appear in the document. Each literal part of a
-pattern is tried both as you typed it and in its stemmed form, so a trailing
-`*` matches a word and its inflections (`invoice*` finds "invoice", "invoices"
-and "invoiced") as well as longer words whose stored term still begins with
-what you typed (`copy*` finds "copyright" alongside "copy" and "copies").
-
-It is still not a plain prefix search over the original text. A trailing `*`
-matches a stored term when either the run you typed or its stemmed form is a
-prefix of that term, so a fragment that stops part-way between the two matches
-neither: `universities*` finds "university" and "universities", which are both
-stored as `univers`, while the shorter `universit*` finds nothing at all. For
-the same reason `happine*` does not find "happiness", which is stored as
-`happi`. And a pattern that requires letters after the wildcard which stemming
-has removed cannot match either: `productname` is stored as `productnam`, so

-    As a value on its own, `now`, `noon`, `midnight` and relative offsets such as `"-3 days"` or `"-1 week"` are accepted by the parser but resolve to a single instant rather than to a span of time, so they match only a document whose timestamp is exactly that instant, which in practice means no documents at all. Quoting does not change this. As a *range bound* they are the opposite of a trap and are what you want: `added:['-1 week' to now]` covers the whole of the last seven days. Spellings like `now-3days` and `"3 days ago"` are rejected outright wherever they appear.

-    whoosh-compat's parse tree, and fuzzy matching was always an
-    approximate, secondary, 0.1-boosted clause). The words come from
-    whoosh_compat's ``free_text_tokens`` over the already-parsed AST,
-    never from the raw query string: raw whoosh grammar (date keywords,

-    the whole query the moment any such construct appeared alongside a
-    typo'd word. The helper also keeps excluded terms out: a ``NOT``'d
-    word must not resurface through the fuzzy clause.
-
-    Chosen trade-off: a term explicitly fielded on one of the default
-    search fields (``correspondent:acme``) contributes its text to the
-    word string UNFIELDED, so the fuzzy clause searches it across all
-    default fields rather than just the one the user named. That is

-    exactly that: no field prefix, pattern, range, grouping or quoting
-    survives, and the boolean keywords that do survive (they are word
-    runs) are lowercased into ordinary terms; see _TANTIVY_KEYWORDS.
-
-    The words are the query's RAW text, not the analyzer's output
-    (``analyzed=False``), because ``index.parse_query`` analyzes whatever
-    it is given and analysis is not idempotent: ``universities`` stems to
-    ``univers``, and handing that back stems it again to ``univ``, a term
-    the index does not contain. ``prefix=True`` hid this as over-broad
-    matching (``univ`` also prefixes ``unicycle``) rather than as no
-    matches at all. Raw text is untokenized, which is why it is cut into
-    word runs above rather than taken whole.
-
-    The ValueError guard stays as insurance (the word string is plain
-    tokens, so tantivy accepting it is expected, not assumed): on a parse
-    failure the fuzzy clause is skipped and the exact/CJK clauses stand,

-"""Regression coverage for the unguarded TEXT-mode highlight query.
-
-parse_simple_text_highlight_query re-parses simple-search tokens through
-Tantivy's query-string parser to build a SnippetGenerator-compatible query.
-Simple-search tokens keep arbitrary punctuation (quotes, colons, brackets,
-slashes), so any token carrying Tantivy query grammar raised an unguarded
-ValueError. The search itself had already succeeded by the time this ran:
-only the highlight step failed, and with the DocumentViewSet.list
-exception handler narrowed elsewhere on this branch, that ValueError now
-reaches the client as a bare 500 rather than a 400.
-
-Covers three angles:
-  - the query builder itself: quoting each token as its own escaped phrase
-    should let it parse instead of raising, for every failure mode a plain-
-    text query can trigger (syntax error, unknown field, unsupported regex).
-  - highlight_hits: even when a token still can't be expressed as a
-    highlight query, the guard must fall back to a query that still
-    produces usable highlight HTML, not silently empty ones.
-  - the real API endpoint: pinning the previously-500 status to 200.
