Name-like tags: same autocapitalization as name in POI editor

[tordans]

Problem

In the POI editor (All Tags and Common Tags), the primary name field gets word-style autocapitalization while typing. Other human-readable name tags—alt_name, old_name, and localized names such as name:en / name:de (name: + language suffix)—behave like plain text, so mappers must capitalize each word manually even though the semantics match name.

This is an issue when mapping in Countries like Cyprus, where street signs are written in Greek and English – and I only know how to writhe English :)

Implementation notes (by Cursor)

• Added TagKey (src/Shared/PresetsDisplay/TagKey.swift):
  • isNameLike(_:) — exact keys name, alt_name, old_name; prefix name: (avoids false positives like namesake / name_source).
  • applyNameLikeTraits — copies autocapitalization/autocorrect from the current feature’s name PresetDisplayKey when present, otherwise defaults to .words / .no.
• All Tags (POIAllTagsViewController): applies name-like traits to the value field when configuring rows.
• Common Tags (POICommonTagsViewController): when a preset field is name-like but the schema supplies .none, overrides to match name on the same feature.
• PresetValueTextField: same override on edit for preset-backed and free-form keys (covers All Tags value editing).
• KeyValueTableCell: name-like keys using the multi-line UITextView path get the same traits.
• Unit tests (TagKeyTests): positive/negative cases for isNameLike.

Testing notes (@tordans)

Automated (on macOS / Xcode):

• Run GoMapTests target; TagKeyTests should pass.

Manual:

1. All Tags: add row name:de → type a multi-word value → keyboard autocapitalization should match name on Common Tags.
2. Common Tags: localized / alternate name preset fields (if shown) should use word caps like name. – Not tested, assumed to work
3. Regression: non-name keys unchanged (e.g. ref, operator). – Not tested, assumed to work
4. False positives: keys like namesake or name_source should not get word caps. – Not tested, assumed to work
