### What problem does this PR solve?
#### Summary
This PR enhances the Semi-automatic metadata filtering mode by allowing
users to explicitly pre-define operators (e.g., contains, =, >, etc.)
for selected metadata keys. While the LLM still dynamically extracts the
filter value from the user's query, it is now strictly constrained to
use the operator specified in the UI configuration.
Using this feature is optional. By default the operator selection is set
to "automatic" resulting in the LLM choosing the operator (as
presently).
#### Rationale & Use Case
This enhancement was driven by a concrete challenge I encountered while
working with technical documentation.
In my specific use case, I was trying to filter for software versions
within a technical manual. In this dataset, a single document chunk
often applies to multiple software versions. These versions are stored
as a combined string within the metadata for each chunk.
When using the standard semi-automatic filter, the LLM would
inconsistently choose between the contains and equals operators. When it
chose equals, it would exclude every chunk that applied to more than one
version, even if the version I was searching for was clearly included in
that metadata string. This led to incomplete and frustrating retrieval
results.
By extending the semi-automatic filter to allow pre-defining the
operator for a specific key, I was able to force the use of contains for
the version field. This change immediately led to significantly improved
and more reliable results in my case.
I believe this functionality will be equally useful for others dealing
with "tagged" or multi-value metadata where the relationship between the
query and the field is known, but the specific value needs to remain
dynamic.
#### Key Changes
##### Backend & Core Logic
- `common/metadata_utils.py`: Updated apply_meta_data_filter to support
a mixed data structure for semi_auto (handling both legacy string arrays
and the new object-based format {"key": "...", "op": "..."}).
- `rag/prompts/generator.py`: Extended gen_meta_filter to accept and
pass operator constraints to the LLM.
- `rag/prompts/meta_filter.md`: Updated the system prompt to instruct
the LLM to strictly respect provided operator constraints.
##### Frontend
- `web/src/components/metadata-filter/metadata-semi-auto-fields.tsx`:
Enhanced the UI to include an operator dropdown for each selected
metadata key, utilizing existing operator constants.
- `web/src/components/metadata-filter/index.tsx`: Updated the validation
schema to accommodate the new state structure.
#### Test Plan
- Backward Compatibility: Verified that existing semi-auto filters
stored as simple strings still function correctly.
- Prompt Verification: Confirmed that constraints are correctly rendered
in the LLM system prompt when specified.
- Added unit tests as
`test/unit_test/common/test_apply_semi_auto_meta_data_filter.py`
- Manual End-to-End:
- Configured a "Semi-automatic" filter for a "Version" key with the
"contains" operator.
- Asked a version-specific query.

Closes#12803
### What problem does this PR solve?
The chat input textarea in the Chat UI (and Embed UI) has a fixed height
and cannot be resized, causing poor UX when users type messages longer
than 2 sentences. The input becomes cramped and difficult to read/edit.
**Root cause:** The `Textarea` component in
[NextMessageInput](cci:1://file:///ragflow/web/src/components/message-input/next.tsx:62:0-290:1)
had `resize-none` and `field-sizing-content` CSS classes that prevented
resizing, and the existing `autoSize` prop was not being utilized.
**Solution:**
- Removed `resize-none` and `field-sizing-content` classes
- Added `autoSize={{ minRows: 1, maxRows: 8 }}` to enable auto-expand
- Added `max-h-40` class to limit maximum height to 160px
The textarea now auto-expands from 1 to 8 rows as users type longer
messages.

### What problem does this PR solve?
Improve image table context.
Current strategy in attach_media_context:
- Order by position when possible: if any chunk has page/position info,
sort by (page, top, left), otherwise keep original order.
- Apply only to media chunks: images use image_context_size, tables use
table_context_size.
- Primary matching: on the same page, choose a text chunk whose vertical
span overlaps the media, then pick the one with the closest vertical
midpoint.
- Fallback matching: if no overlap on that page, choose the nearest text
chunk on the same page (page-head uses the next text; page-tail uses the
previous text).
- Context extraction: inside the chosen text chunk, find a mid-sentence
boundary near the text midpoint, then take context_size tokens split
before/after (total budget).
- No multi-chunk stitching: context comes from a single text chunk to
avoid mixing unrelated segments.
