fix(presets): coerce non-string catalog tags before joining (#3743)

* fix(presets): coerce non-string catalog tags before joining

Preset catalog payloads are user-editable YAML/JSON, so a `tags:` list
can legitimately contain non-strings (e.g. numeric tags). The preset
list/search/info display paths and the catalog search backend joined
tags with a raw `", ".join(...)` / used `t.lower()`, which raised
`TypeError: sequence item N: expected str instance, int found` (or
`AttributeError` on `.lower()`) and crashed the command.

Sibling command surfaces already guard this — extensions, integrations,
and workflows coerce with `str(t) for t in ...`. This aligns presets:

- `_commands.py`: `preset list`, `preset search`, and both `preset info`
  branches now join `str(t) for t in ...`.
- `__init__.py` `PresetCatalog.search`: tag filter uses `str(t).lower()`
  and the searchable-text join coerces tags to `str`.

Adds regression tests driving `preset search` and `preset info` through
CliRunner with numeric tags; both fail before the fix with the TypeError.
