fix(frontend): use case-insensitive regex in getBlockCardByName

beautifyString capitalizes each word (e.g. "Add To Dictionary") but
tests may pass names with different casing (e.g. "Add to Dictionary").
Playwright hasText with a string is case-insensitive but with a regex
it is case-sensitive, so add the "i" flag.

@@ -52,43 +52,11 @@ Examples:
 You can embed a reference inside any string argument, or use it as the entire
 value.  Multiple references in one argument are all expanded.
 
-**Structured data**: When the **entire** argument value is a single file
-reference (no surrounding text), the platform automatically parses the file
-content based on its extension or MIME type.  Supported formats: JSON, JSONL,
-CSV, TSV, YAML, TOML, Parquet, and Excel (.xlsx — first sheet only).
-For example, pass `@@agptfile:workspace://<id>` where the file is a `.csv` and
-the rows will be parsed into `list[list[str]]` automatically.  If the format is
-unrecognised or parsing fails, the content is returned as a plain string.
-Legacy `.xls` files are **not** supported — only the modern `.xlsx` format.
+**Type coercion**: The platform automatically coerces expanded string values
+to match the block's expected input types.  For example, if a block expects
+`list[list[str]]` and you pass a string containing a JSON array (e.g. from
+an @@agptfile: expansion), the string will be parsed into the correct type.
 
-**Type coercion**: The platform also coerces expanded values to match the
-block's expected input types.  For example, if a block expects `list[list[str]]`
-and the expanded value is a JSON string, it will be parsed into the correct type.
-
-### Media file inputs (format: "file")
-Some block inputs accept media files — their schema shows `"format": "file"`.
-These fields accept:
-- **`workspace://<file_id>`** or **`workspace://<file_id>#<mime>`** — preferred
-  for large files (images, videos, PDFs). The platform passes the reference
-  directly to the block without reading the content into memory.
-- **`data:<mime>;base64,<payload>`** — inline base64 data URI, suitable for
-  small files only.
-
-When a block input has `format: "file"`, **pass the `workspace://` URI
-directly as the value** (do NOT wrap it in `@@agptfile:`). This avoids large
-payloads in tool arguments and preserves binary content (images, videos)
-that would be corrupted by text encoding.
-
-Example — committing an image file to GitHub:
-```json
-{
-  "files": [{
-    "path": "docs/hero.png",
-    "content": "workspace://abc123#image/png",
-    "operation": "upsert"
-  }]
-}
-```

 - When using the Task tool, NEVER set `run_in_background` to true.

-"""Parse file content into structured Python objects based on file format.

-Used by the ``@@agptfile:`` expansion system to eagerly parse well-known file
-formats into native Python types *before* schema-driven coercion runs.  This
-lets blocks with ``Any``-typed inputs receive structured data rather than raw
-strings, while blocks expecting strings get the value coerced back via
-``convert()``.
-
-Supported formats:
-
-- **JSON** (``.json``) — arrays and objects are promoted; scalars stay as strings
-- **JSON Lines** (``.jsonl``, ``.ndjson``) — each non-empty line parsed as JSON;
-  when all lines are dicts with the same keys (tabular data), output is
-  ``list[list[Any]]`` with a header row, consistent with CSV/Parquet/Excel;
-  otherwise returns a plain ``list`` of parsed values
-- **CSV** (``.csv``) — ``csv.reader`` → ``list[list[str]]``
-- **TSV** (``.tsv``) — tab-delimited → ``list[list[str]]``
-- **YAML** (``.yaml``, ``.yml``) — parsed via PyYAML; containers only
-- **TOML** (``.toml``) — parsed via stdlib ``tomllib``
-- **Parquet** (``.parquet``) — via pandas/pyarrow → ``list[list[Any]]`` with header row
-- **Excel** (``.xlsx``) — via pandas/openpyxl → ``list[list[Any]]`` with header row
-  (legacy ``.xls`` is **not** supported — only the modern OOXML format)
-
-The **fallback contract** is enforced by :func:`parse_file_content`, not by
-individual parser functions.  If any parser raises, ``parse_file_content``
-catches the exception and returns the original content unchanged (string for
-text formats, bytes for binary formats).  Callers should never see an
-exception from the public API when ``strict=False``.
