add type tags to all @cell components

[joamatab]

Summary

• Adds tags={"type": "<filename>"} to all @gf.cell and @gf.cell_with_module_name decorators
• Type is derived from the source filename (e.g., waveguides.py → "waveguides", couplers.py → "couplers")
• Enables filtering and categorization of components by type

Mirrors the change in gdsfactory: gdsfactory/gdsfactory@4c216c5ef

Test plan

• Verify all cells still instantiate correctly via make test
• Check that tags appear in cell metadata

Reviewer's Guide

Annotates all @gf.cell component decorators with a per-file "type" tag derived from the source filename to enable component categorization and filtering, without changing cell implementations or signatures.

File-Level Changes

Change	Details	Files
Add "type" metadata tags to all @gf.cell decorators across CSPDK cells to categorize components by their source file type.	Wrap every @gf.cell decorator invocation with tags={"type": "<module_basename>"} while keeping function bodies and signatures unchanged. Standardize type tag values to match module names such as "cells", "waveguides", "couplers", "die", "containers", "fixed", "spirals", "tapers", "grating_couplers", "heaters", "mmis", "rings", "text", "mzis", and "vias". Ensure consistency between cband and oband variants by applying the same tagging scheme in corresponding modules.	cspdk/si500/cells.py cspdk/sin300/cells.py cspdk/si220/cband/cells/waveguides.py cspdk/si220/oband/cells/waveguides.py cspdk/si220/cband/cells/die_with_pads.py cspdk/si220/oband/cells/containers.py cspdk/si220/oband/cells/die_with_pads.py cspdk/si220/cband/cells/containers.py cspdk/si220/cband/cells/couplers.py cspdk/si220/cband/cells/fixed.py cspdk/si220/cband/cells/spirals.py cspdk/si220/cband/cells/tapers.py cspdk/si220/oband/cells/couplers.py cspdk/si220/oband/cells/fixed.py cspdk/si220/oband/cells/spirals.py cspdk/si220/oband/cells/tapers.py cspdk/si220/cband/cells/grating_couplers.py cspdk/si220/cband/cells/heaters.py cspdk/si220/cband/cells/mmis.py cspdk/si220/cband/cells/rings.py cspdk/si220/cband/cells/text.py cspdk/si220/oband/cells/grating_couplers.py cspdk/si220/oband/cells/heaters.py cspdk/si220/oband/cells/mmis.py cspdk/si220/oband/cells/rings.py cspdk/si220/oband/cells/text.py cspdk/si220/cband/cells/mzis.py cspdk/si220/cband/cells/vias.py cspdk/si220/oband/cells/mzis.py cspdk/si220/oband/cells/vias.py

Hey - I've left some high level feedback:

• To reduce repetition and make future updates easier, consider defining a module-level constant for the tag (e.g. TAGS = {"type": "waveguides"}) and reusing it across all @gf.cell decorators in each file instead of inlining the same dict literal many times.

## Overall Comments
- To reduce repetition and make future updates easier, consider defining a module-level constant for the tag (e.g. `TAGS = {"type": "waveguides"}`) and reusing it across all `@gf.cell` decorators in each file instead of inlining the same dict literal many times.
