feat: vrl support for visualization (#10237)

### **User description** Design at : https://github.com/openobserve/designs/tree/main/visualization-vrl-support ### **PR Type** Enhancement ___ ### **Description** - Always default to table chart with VRL functions - Preserve and propagate VRL function query across UI - Enable dynamic columns for VRL-based table charts - Remove visualization-mode restrictions for function editor ___ ### Diagram Walkthrough ```mermaid flowchart LR VRL["VRL Function Present?"] VRL -- "yes" --> Table["Force Table Chart"] Table -- "on table" --> DynCols["Enable Dynamic Columns"] VRL -- "no" --> OtherCharts["Allow Other Chart Types"] ``` <details> <summary><h3> File Walkthrough</h3></summary> <table><thead><tr><th></th><th align="left">Relevant files</th></tr></thead><tbody><tr><td><strong>Enhancement</strong></td><td><table> <tr> <td> <details> <summary><strong>useDashboardPanel.ts</strong><dd><code>Force table chart for VRL functions</code>                                            </dd></summary> <hr> web/src/composables/useDashboardPanel.ts <ul><li>Added VRL check in determineChartType<br> <li> Default to table when VRL functions exist</ul> </details> </td> <td><a href="https://github.com/openobserve/openobserve/pull/10237/files#diff-fbba1700750053b9eaf38ddd30dab84531bc44131c795ebb713811e4930cd7cb">+5/-0</a>      </td> </tr> <tr> <td> <details> <summary><strong>Index.vue</strong><dd><code>Propagate and handle VRL function queries</code>                                </dd></summary> <hr> web/src/plugins/logs/Index.vue <ul><li>Copy and clear <code>vrlFunctionQuery</code> on query update<br> <li> Force table type and set <code>table_dynamic_columns</code><br> <li> Preserve <code>vrlFunctionQuery</code> in visualization flow</ul> </details> </td> <td><a href="https://github.com/openobserve/openobserve/pull/10237/files#diff-0323c3da69b369843c5d72bf4df5b00ca6b5147192a213baf331659ecf92af62">+70/-2</a>    </td> </tr> <tr> <td> <details> <summary><strong>SearchBar.vue</strong><dd><code>Enable VRL editor in visualize mode</code>                                            </dd></summary> <hr> web/src/plugins/logs/SearchBar.vue <ul><li>Always allow editing VRL function editor<br> <li> Removed visualize-mode warning overlay</ul> </details> </td> <td><a href="https://github.com/openobserve/openobserve/pull/10237/files#diff-81893de4edf186b0556f610acb280c87baa2ffe67d3b48a60a866094c7635baf">+1/-26</a>    </td> </tr> <tr> <td> <details> <summary><strong>TransformSelector.vue</strong><dd><code>Lift transform restrictions in visualize mode</code>                        </dd></summary> <hr> web/src/plugins/logs/TransformSelector.vue <ul><li>Removed disable state for transform toggle/save in visualize<br> <li> Removed visualize-mode tooltip restrictions</ul> </details> </td> <td><a href="https://github.com/openobserve/openobserve/pull/10237/files#diff-0037d8dd9cfbacc26309b26e98ae953e7ccbd0891ac2fd01c6314ebd7eed9d2c">+3/-13</a>    </td> </tr> <tr> <td> <details> <summary><strong>VisualizeLogsQuery.vue</strong><dd><code>Restrict chart types when VRL functions present</code>                    </dd></summary> <hr> web/src/plugins/logs/VisualizeLogsQuery.vue <ul><li>Block non-table chart selection if VRL functions exist<br> <li> Show error and reset to table on invalid type switch</ul> </details> </td> <td><a href="https://github.com/openobserve/openobserve/pull/10237/files#diff-979b01d943d58c5d70faeeac5948b7f02f0b2392a12b84ef07ba7f7393ab0261">+14/-0</a>    </td> </tr> </table></td></tr></tr></tbody></table> </details> ___ ___ ### **PR Type** Enhancement, Tests ___ ### **Description** -
