Fix Widget Docs

[Lightning11wins]

Changes:

• Fixed some htdrv_*.c files that registered their widget's events/actions incorrectly.
• Improved the DTD spec for widgets.xml and updated the entire file to follow the new spec.
• Added many missing widgets, properties, events, and actions.
• Added detailed information about event and action parameters where relevant.
• Reformatted widgets.xml to a consistent format.

Results:
When running the unfinished doc-report script on master, we get a lot of doc issues:

========

After this PR, we have significantly fewer issues:

========

Note: The issue count will fall even further after clean up from other PRs like #90 is merged:

========

Note 2: All of these changes were made on the fix-widget-docs-dev branch, which is based off of several other branches that aren't merged yet. In order to make this branch, I had to cherry-pick all the commits from that branch onto this branch, which is based off of master. This was a very difficult and technical process, so if you notice any bizarre changes on this branch, please let me know because that might be the cause of the issue.

Note 3: When merging, ensure that 6fab4ecaa4fe827adfb9b828bf86e88d4b3c8b2a is added to the ignore diffs list because it contains the general reformat of widgets.xml.

Note 4: These issues were detected using the script in PR #101.

Greptile Summary

This PR corrects event/action registrations in several htdrv_*.c files to match what their JS counterparts actually fire, removes dead osrc-rule code, and substantially expands widgets.xml with missing widgets, properties, events, and actions.

• C driver fixes: htdrv_editbox.c correctly updates DataModify params; htdrv_fileupload.c aligns action/event names with the JS; htdrv_form.c adds Disable/Enable actions and drops the spurious QueryExec event; htdrv_window.c removes the unused NoInit param.
• Dead code removal: The #if 00 osrc-rule block in htdrv_osrc.c and its corresponding wgtrAddType call in wgtdrv_osrc.c are cleaned up.
• widgets.xml: Reformatted to a consistent structure and expanded with many previously missing entries.

Confidence Score: 5/5

Safe to merge — all changes are documentation metadata corrections and dead code removal with no impact on runtime logic.

Every changed C file only calls htrAddEvent, htrAddAction, and htrAddParam — registration calls that feed the doc-report tool. The two remaining mismatches are doc-accuracy issues, not runtime regressions. The JS changes are minor and semantically safe.

htdrv_textarea.c has a leftover param name mismatch (NewValue vs Value) that the editbox fix was meant to address in both files. htdrv_scrollpane.c registers Scroll and Wheel events that have no JS implementation yet.

Important Files Changed

Filename	Overview
centrallix/htmlgen/htdrv_textarea.c	Renames event from Modified to DataModify but still uses NewValue instead of Value and omits FromKeyboard/FromOSRC params — mismatches what the JS actually fires.
centrallix/htmlgen/htdrv_editbox.c	Renames event from Modified to DataModify and corrects params (Value, OldValue, FromKeyboard, FromOSRC) to match what htdrv_editbox.js fires.
centrallix/htmlgen/htdrv_fileupload.c	Renames Reset action to Clear and replaces Success event with UploadComplete, UploadError, and Change — all matching the JS registrations in htdrv_fileupload.js.
centrallix/htmlgen/htdrv_form.c	Adds Disable and Enable actions (matching ia.Add in JS) and removes QueryExec as an event (it is an action in JS, not an event).
centrallix/htmlgen/htdrv_scrollpane.c	Adds Scroll, Wheel events and ScrollTo action; ScrollTo is implemented in JS but Scroll and Wheel have no JS counterpart, making them phantom registrations.
centrallix/htmlgen/htdrv_window.c	Removes NoInit param from SetVisibility; NoInit is absent from htdrv_window.js, so the removal is correct.
centrallix/htmlgen/htdrv_osrc.c	Removes a large #if 00 dead-code block for osrc-rule and a commented-out pObjQuery variable, leaving cleaner render logic.
centrallix/wgtr/wgtdrv_osrc.c	Removes wgtrAddType(name, "osrc-rule") registration; consistent with the removal of the dead osrc-rule handler in htdrv_osrc.c.
centrallix-os/sys/js/htdrv_window.js	Refactors wn_closewin and wn_openwin to use spread syntax instead of mutating aparam in place when invoking SetVisibility.
centrallix-os/sys/js/htdrv_editbox.js	Minor comment cleanup — clarifies that aparam.Description drives the description update via SetValueDescription.
centrallix-doc/Widgets/widgets.xml	Large reformatting and expansion: adds many missing widgets, properties, events, and actions, and improves the DTD spec for consistent structure.
