Faster Edit Security dialog for large taxonomies - #6271
Problem: opening the dialog took ~30 s on Linux/GTK with many taxonomies — an SWT Combo is not virtual, so each classification became a native row and GTK recomputed its preferred size per insert (quadratic), and computeSize asked that widget on every refresh.
Picker replaced: label + link opening ListSelectionDialog (virtual table, search field) — unlimited classifications, no native widget in the layout, cheap computeSize.
Selection persists: picker uses WritableValue, so the value-change event fires and the binding updates ClassificationLink.classification; validators re-run immediately.
Lazy tabs: only the visible tab builds its controls; the other four are created on first open.
Cheaper sorting: TaxonomyDesignation caches path names and an index map instead of List.indexOf per comparison.
Dialog pre-selection: ListSelectionDialog.setInitialSelection, sorted by natural/name/weight.
Messages: new EditWizardMasterDataSelectClassification in base and all locales; missing-classification text no longer mentions a drop-down list.
Test: TaxonomyDesignationCacheTest covers cache and index order.
The classification picker in the Edit Security dialog no longer uses a
native combo box. Each classification used to be inserted as its own
toolkit widget, and the layout asked the native widget for its preferred
size on every refresh, so opening the dialog and switching to the
Taxonomies tab grew quadratically with the number of classifications.
- The drop-down is replaced by a label plus a link that opens a
searchable selection dialog. The list is virtual, so its size no longer
affects opening time, and all classifications stay reachable through the
search field.
- Classification path names are calculated once per classification
instead of on every label and filter call.
Sorting by taxonomy order uses a lookup index instead of scanning the
classification list inside the comparator.
- The validation rules are unchanged: a classification must be
selected, may not be used twice, and the weights must add up to 100%.

Walkthrough
The security editor replaces classification combo boxes with a selection dialog, caches classification path names and taxonomy positions, validates taxonomy assignments, and creates dialog pages on demand. Localized prompts and tests are updated.

Layer / File(s)
Summary
Cache designation data and validate assignments name.abuchen.portfolio.ui/.../EditSecurityModel.java, name.abuchen.portfolio.ui.tests/.../TaxonomyDesignationCacheTest.java
TaxonomyDesignation caches classification path names and taxonomy positions. Assignment validation checks for missing or duplicate classifications, non-positive weights, and totals above 100%. Tests cover lookup behavior and assignment links.
Support initial dialog selection name.abuchen.portfolio.ui/dialogs/ListSelectionDialog.java
ListSelectionDialog adds an API to set an initial element and selects it when the table viewer opens.
Wire the taxonomy selector name.abuchen.portfolio.ui/.../SecurityTaxonomyPage.java, name.abuchen.portfolio.ui/Messages.java, name.abuchen.portfolio.ui/messages*.properties
The taxonomy page uses a selection link and dialog. The dialog preselects the current classification and sorts by name or taxonomy position. A selection updates the displayed path and tooltip. Resource bundles add the selector label and revise the missing-classification prompt.
Validate assignments and create pages on demand name.abuchen.portfolio.ui/.../EditSecurityDialog.java
EditSecurityDialog displays validation status, blocks saving when assignments are invalid, and creates page controls when a tab is selected.

portfolio-performance/portfolio#6261 — The changes replace taxonomy combo boxes with a selection dialog and defer creation of controls for unselected pages, addressing the reported slow taxonomy editing and dialog opening.
Priority: Normal
Merge Risk: Minimal · up to 65c45
The dialog now validates taxonomy assignments before saving, even if the taxonomy tab was never opened. Existing assignments with invalid weights can no longer be saved unchanged from another tab. No remaining merge-blocking risk was identified. Verification on Linux with a large taxonomy is still advisable.

- Around line 507-509: Update `doSetValue` to notify observers when the
classification changes, passing the old and new values so the binding in
`setupClassificationMultiValidator` updates `ClassificationLink.classification`.
Alternatively, use `WritableValue` to provide the required change notification.

Opening the Edit Security dialog realized the widgets of all five
tabs although only one of them is visible. On GTK a combo box has no
virtual mode: every item becomes a native toolkit widget and the
widget recomputes its preferred size while the items are inserted, so
the hidden tabs with their currency and quote feeds added a delay
before the dialog appeared. Controls are now created when a tab is
opened for the first time; the initially selected tab is realized
before beforePage() so a dialog that starts on the quote
configuration keeps working.

The validators of the taxonomy tab are created together with the
controls of that tab, which are no longer created when the dialog is
opened. An existing assignment whose weights exceed 100 % would then be
saved without any error shown. The rules are checked on the model, both
for the initial state of the dialog and before the changes are applied.
